A solenoid valve includes a main valve having a valve member which switches over flow paths by contacting with and separating from valve seats in a valve casing, a solenoid operating portion to drive the valve member, and a manually-operated device including an operation rod air-tightly and slidably accommodated in a rod-insertion hole provided in the valve casing and abuts against an end surface of a movable iron core to push the movable iron core in its axial direction, and an operating member movably mounted to a mounting surface of the valve casing to drive the operation rod.

1. A solenoid valve comprising:a main valve including a valve member configured to open and close a valve seat in a valve casing;a solenoid operating portion including a movable iron core configured to drive said valve member; anda manually-operated device including an operation rod configured to be accommodated in a rod-insertion hole provided in the valve casing, and an operating member configured to operate said operation rod, said operating member including a slide member configured to be movably mounted to a mounting surface provided in a side surface of said valve casing at a position adjacent to the rod-insertion hole, said slide member including a body, and a connection plate extending substantially perpendicularly from the body, said connection plate configured to interlock with the operation rod,wherein when said operating member is manually-operated, said slide member and said operation rod move in a direction substantially parallel to an axis of the movable iron core such that said operation rod abuts against said movable iron core to displace the movable iron core to actuate said valve member.2. A solenoid valve according to claim 1, wherein said rod-insertion hole is provided at a position opposed to a tip end surface of said movable iron core such that an axis of said rod-insertion hole is directed in the direction substantially parallel to the axis of said movable iron core.3. A solenoid valve according to claim 2, wherein an operating portion mounting opening which is thin and long in an axial direction of said movable iron core is formed in said mounting surface of said valve casing at the position adjacent to said rod-insertion hole, opposite sidewalls of said mounting opening in its widthwise direction are respectively formed with engaging grooves,said slide member includes a pair of pawls which are slidably engaged with said engaging grooves, said slide member is mounted to said mounting opening such that the slide member can move in a longitudinal direction of said mounting opening, and is resiliently pushed toward a non-operation position by a spring.4. A solenoid valve according to claim 3, wherein said rod-insertion hole is provided at its portion of hole wall with an opening which is in communication with said operating portion mounting opening, said connection plate is engaged with said operation rod through this opening,said operation rod is provided at its outer peripheral surface with a seal member and a connection groove with which a U-shaped notch of said connection plate.5. A solenoid valve according to claim 3, wherein said operating member includes, in addition to said slide member, a second member for displacing said slide member, said second member is disposed at a position adjacent to said slide member in said operating portion mounting opening such that said second member can turn in a state in which said second member abuts against said slide member, and by this turning operation, said slide member is displaced between an operation position and said non-operation position, and is locked at the operation position and the non-operation position.6. A solenoid valve according to claim 5, wherein said slide member includes a partially circular opening, said second member is fitted into said opening,said second member is provided at its upper surface with an operating portion for turning and operating, and a cam-acting portion which abuts against an end wall of said operating portion mounting opening and turns, and by eccentric motion caused by the turning motion of said cam-acting portion, said second member moves to move said slide member to the operation position and to the non-operation position.7. A solenoid valve according to claim 5, wherein said valve casing has a pair of sidewalls rising from said mounting surface at positions of opposite sides of said operating portion mounting opening, in said mounting surfacesaid second member includes a stopper which abuts against said sidewalls at a turning position where said slide member is moved to said operation position and said non-operation position.8. A solenoid valve according to claim 6, wherein said valve casing has a pair of sidewalls rising from said mounting surface at positions of opposite sides of said operating portion mounting opening, in said mounting surfacesaid second member includes a stopper which abuts against said sidewalls at a turning position where said slide member is moved to said operation position and said non-operation position.
