<p>PURPOSE:To change over a lock lever to locking and unlocking, and to obtain a super locking device easily by engaging and disengaging the upper engaging section of a piece with and from the engaging section of the front end of an engaging lever by driving a motor. CONSTITUTION:When locking is operated by a key under an unlocked state, electricity is conducted through a motor 1 and a driving shaft 2 is rotated, and a fan-shaped worm wheel 9 is rocked in the direction of (b) through a worm gear 7 and a circular gear 13. A boss 15 is pushed at the right end of a circular slot 16, and the position of a lock lever is displaced from an unlocked position to a locked position. A gear 8 is turned at that time, and a vertically movable body 35 fitted to a guide groove 40 is moved vertically while a piece 34 is moved upward. The upper engaging section 41 of the piece 34 is fitted into an engaging recessed section 33 from a lower section, and the front-end engaging section 27 of an engaging lever 23 sprung out by the elastic force of a strut spring 26 is interlinked with the groove 39 of the piece 34. The piece 34 is interlinked with a super lock lever 19, and the evolution of the lock lever engaged with the lock lever 19 to an unlocked position operated from the outside is made impossible by the boss 15.</p> |
