PROBLEM TO BE SOLVED: To provide an operational mechanism for a movable body which can be automatically returned to a closed position after an opened state. SOLUTION: One end of a reverse spring 32 is attached to a hook member 12, and the other end of the reverse spring 32 is attached to a gear member 54. The gear member 54 turns by pressing the hook member 12 from a pushed position and changes the position where an energizing force of the reverse spring 32 is applied (energizing position) with respect to the turning center (shaft 24) of the hook member 12. Thus, the rotational force rotating the hook member 12 to a closed position or an opened position is generated in the reverse spring 32. Thereby, the hook member 12 can be automatically returned to the closed position after the lapse of a predetermined time after the opened state of the hook member 12. COPYRIGHT: (C)2010,JPO&INPIT
