PROBLEM TO BE SOLVED: To reduce size and cost of a driving mechanism by reducing a maximum load on the driving mechanism thereby making it possible to employ a driving source of a relatively small output. SOLUTION: When a door is to be closed, a sector gear 26 is rotated with a driving force of a motor 27 in the direction of arrow D1 to move a closing lever from a standby position to a working position through a wire 21. Here, a spring 29 assist the rotation of the sector gear 26 so that the load on the motor 27 is alleviated. When the door is closed, the sector gear 26 is rotated wit the driving force of the motor 27 in the direction of arrow D2 so that the closing lever is returned to the standby position. |
