The present invention provides a ground terminal fitting capable of being fixed to a ground member through a simple operation while permitting production cost to be reduced, and a ground device having the ground terminal fitting. The ground terminal fitting comprises a terminal body surrounding a through-hole, a clamping piece having a rising portion rising from an outer peripheral edge of the terminal body and a distal end portion extending inwardly from the rising portion along the terminal body, and a clampable piece located adjacent to the clamping piece in a circumferential direction of the terminal body. The clamping piece is adapted to clamp, when the ground terminal fitting is superimposed on a second ground terminal fitting, a clampable piece of the second ground terminal fitting to prevent a relative displacement between the ground terminal fittings. The distal end portion is adapted to contact the ground member penetrating through the through hole to prevent a relative rotation of the ground terminal fitting with respect to the ground member.

1. A ground terminal fitting designed to be fixed to a common ground member together with a second ground terminal fitting in a mutually superimposed manner, comprising: an annular-shaped terminal body formed with a through-hole for allowing the ground member to penetrate therethrough;a cable-fastening section having a bottom wall, and a pair of barrel-shaped walls each rising from the bottom wall, the cable-fastening section being adapted to be fastened to an end of an electric cable based on plastic deformation of the pair of barrel-shaped walls;a clamping section having a rising portion rising from an outer peripheral edge of the terminal body in a direction opposite to that of the barrel-shaped walls of the cable-fastening section, and a distal end portion extending from the rising portion inwardly along the terminal body; anda clampable section formed along the outer peripheral edge to be located adjacent to the clamping section in a circumferential direction of the terminal body,wherein the clamping section is adapted to clamp, when the ground terminal fitting is superimposed on the second ground terminal fitting, a clampable section of the second ground terminal fitting to prevent a relative displacement between the superimposed ground terminal fittings, and the distal end portion of the clamping section is adapted to touch the ground member, when the ground member is set to penetrate through the through-hole, to prevent the ground terminal fitting having the clamping section from being rotated with respect to the ground member. 2. The ground terminal fitting as defined in claim 1, wherein: one of the clamping section and the clampable section is formed with a locking protrusion protruding toward the other; andthe other section of the clamping section and the clampable section is formed with a locking hole which is adapted to be capable of being engaged, when the ground terminal fitting is superimposed on a second ground terminal fitting having a same configuration as that thereof, with the locking protrusion of the second ground terminal fitting. 3. The ground terminal fitting as defined in claim 1, which further comprises an auxiliary clamping section and an auxiliary clampable section each continued to the outer periphery of the annular-shaped terminal body and located on an opposite side of a corresponding one of the lamping section and the clampable section, the auxiliary clamping section being adapted to cramp, when the clamping section clamps the clampable section of a second ground terminal fitting having a same configuration as that of the ground terminal fitting, the auxiliary clampable section of the second ground terminal fitting. 4. The ground terminal fitting as defined in claim 3, which further comprises a neck section connecting the terminal body and the cable-fastening section, wherein: the auxiliary clamping section has a rising portion rising from an edge of the neck section in a direction opposite to the rising direction of the barrel-shaped walls, and a distal end portion extending inwardly along the neck section; andthe auxiliary clampable section extends continuously from the neck section in the circumferential direction along the outer peripheral edge of the terminal body,and wherein:the auxiliary clamping section is adapted to clamp, when the ground terminal fitting is superimposed on a second ground terminal fitting having a same configuration as that thereof, the auxiliary clampable section of the second ground terminal fitting to prevent a relative displacement with respect to the second ground terminal fitting; andthe extension segment of the auxiliary clamping section is adapted to touch the ground member penetrating through the through-hole to prevent a rotation of the ground terminal fitting with respect to the ground member. 5. The ground terminal fitting as defined in claim 4, which further comprises a superimposed segment extending from a part of the edge of the neck section on an opposite side of a remaining part of the edge connected to the extension segment, the superimposed segment being superimposed onto the neck section to extend between the neck section and the extension segment to make up a reinforcing portion which reinforces the neck section in cooperation with the extension segment. 6. A ground device comprising a plurality of ground terminal fittings formed in a same configuration and adapted to be superimposed on each other to form a superimposed assembly, and a common ground member being provided on a given support base and having a portion adapted to be inserted into respective through-holes of the ground terminal fittings included in the superimposed assembly, wherein: each of the ground terminal fittings is comprised of the ground terminal fitting as defined in claim 1; andthe ground member has a portion adapted to be engaged with the clamping section of a lowermost one of the ground terminal fittings in the superimposed assembly to prevent a rotation of the lowermost ground terminal fitting. 7. The ground device as defined in claim 6, wherein the ground member includes: a shaft portion disposed to protrude from the support base and adapted to be inserted into the through-holes of the ground terminal fittings; a rotation-blocking portion located on the support base and around the shaft portion; and a fastening portion adapted to fasten the ground terminal fittings penetrated by the shaft portion, from the side of a distal end of the shaft portion, and wherein the rotation-blocking portion is adapted to engaged with the clamping section of the lowermost ground terminal fitting to block a rotation of the lowermost ground terminal fitting. 8. The ground device as defined in claim 7, wherein: the shaft portion is comprised of a stud bolt having opposite ends each formed with a screw groove;the rotation-blocking portion is comprised of a fixed nut fixed onto the support base and screwed with one of the ends of the stud bolt while receiving therein the one end; andthe fastening portion is comprised of a fastening nut capable of being screwed with the other end of the stud bolt. 9. A ground device comprising a plurality of ground terminal fittings formed in a same configuration and adapted to be superimposed on each other to form a superimposed assembly, and a common ground member being provided on a given support base and having a portion adapted to be inserted into respective through-holes of the ground terminal fittings included in the superimposed assembly, wherein: each of the ground terminal fittings is comprised of the ground terminal fitting as defined in claim 3; andthe ground member includes a stud bolt disposed to protrude from the support base and adapted to be inserted into the through-holes of the ground terminal fittings, a fixed nut fixed onto the support base and screwed with one of opposite ends of the stud bolt while receiving therein the one end, and a fastening nut adapted to be capable of being screwed with the other end of the stud bolt to fasten the ground terminal fittings on the shaft portion inserted therein, from the side of a distal end of the shaft portion,and wherein:the fixed nut has an outer peripheral surface having a pair of plane side surfaces oriented in respective opposite directions; anda distance between the distal end portion of the clamping section and the distal end portion of the auxiliary clamping section is set to allow the fixed nut to be interposed between the respective distal end portion and to be approximately equal to a distance between the pair of planar-shaped side surfaces of the fixed nut.
