A retracting device has a retracting main body including a case, a hook disposed in the case, an urging member, and a braking device including a cylinder and a piston rod; and a protruding portion engaging with and disengaging from the hook in a middle of a movement of a moving body relative to an enclosure. The hook is switched between a retracting position allowing the moving body to move in an engaged state with the protruding portion, and a standby position disallowing the moving body to move in a disengaged state. The hook is in the standby position when disengaged from the protruding portion in a state wherein the piston rod is entered with respect to the cylinder, and has reduced a protruding dimension, and is switchable to the retracting position from the standby position when the piston rod increases the protruding dimension relative to the cylinder.

1. A retracting device, comprising: a retracting main body including a case placed on an enclosure side, a hook comprising an axis portion protruding laterally from the hook, a protrusion situated adjacent to the axis portion and protruding laterally from the hook, and a concave portion, an urging member urging the hook in a longitudinal direction of the case, a braking device, a guide groove formed in the case along the longitudinal direction of the case, and another guide groove formed in the case parallel to the guide groove, wherein the hook, the urging member and the braking device are disposed in the case; anda protruding portion placed on a moving body side, and engaging with and disengaging from the concave portion of the hook in a middle of a movement of a moving body relative to an enclosure,wherein the axis portion is held in the guide groove to slidably move therein, and the hook is switched between a retracting position allowing the moving body to move in an engaged state with the protruding portion, and a standby position prohibiting the moving body to move in a disengaged state,the protrusion is held in the another guide groove to slidably guide the protrusion therein, and switching the hook from the standby position to the retracting position,the braking device includes a piston damper having a cylinder and a piston rod, and either one of the cylinder or the piston rod is fixed in the case, and the other is slidably disposed and the hook is pivotally supported on an end side thereof, andthe hook is in the standby position in which the hook is disengaged from the protruding portion in a state wherein the piston rod is entered with respect to the cylinder to reduce a protruding dimension, and is switchable to the retracting position from the standby position when the piston rod increases the protruding dimension relative to the cylinder. 2. A retracting device according to claim 1, wherein the urging member includes a compression spring, and is disposed along the piston damper, and one end is locked on a slidably disposed side among the cylinder and the piston rod, and the other end is immovably engaged. 3. A retracting device according to claim 2, wherein the compression spring is disposed on an outer circumference of the other slidably disposed side among the cylinder and the piston rod. 4. A retracting device according to claim 2, further comprising a guide axis connected to the other slidably disposed side among the cylinder and the piston rod, and disposed approximately parallel to the piston damper, wherein the compression spring is disposed on an outer circumference of the guide axis. 5. A retracting device according to claim 3, wherein the other slidably disposed side is the piston rod among the cylinder and the piston rod, and the piston rod comprises an extension rod connected on a coaxial line. 6. A retracting main body according to claim 1, which is used for the retracting device assisting a moving operation of the moving body relative to the enclosure by an urging force. 7. A retracting main body according to claim 1, further comprising a locking portion formed at a front end of the another guide groove, wherein the protrusion of the hook engages the locking portion when the hook is in the standby position, andthe protrusion of the hook moves slidably in the another guide groove when the hook is in the retracting position. 8. A retracting main body according to claim 1, wherein the guide groove extends linearly so that the axis portion moves only linearly, and the hook tilts around the axis portion.
