<p>PURPOSE:To execute stable locking operation by constituting so that locking of a member to be locked is released by moving a locking member through an auxiliary member, immediately after an operation of a releasing member is started, and thereafter, both the members are reset to the original state and relocking of the member to be locked is executed, when the releasing member is detached from the auxiliary member. CONSTITUTION:Before the operation of a releasing member (1), in this case, a driving force from a driving source is not transferred yet to the releasing member, and the releasing member 4 does not advance. At the time of start of an advance of the releasing member - completion of the advance (2), when the driving force from the driving source is transferred to the releasing member 4 through a power plate P, the releasing member starts to advance, and starts to press an engaged part 11b of an auxiliary member 11 which is engaged until that time. Subsequently, when the releasing member moves backward (3), the releasing member 4 which advances in said (2) starts to move backward thereafter. Soon after that, the releasing member 4 contacting with a part to be pressed 11c of the auxiliary member 11 passes the part to be passed 11c clockwise together with its subsequent moving-back operation.</p> |
