<p>PURPOSE:To prevent unlocking operation induced by unlawful behavior definitely and protect components from being damaged by unlawful behavior based on simple structure. CONSTITUTION:A deformable deformation unit 4e is installed to a locking/ unlocking lever 4 so as to absorb an operation force in the unlocking direction, if an excessive load is exerted from a lock knob side, for example, when a key cylinder is located at a locked position and restrained from moving in the unlocking direction. When the locking/unlocking lever 4 is forced to move in the unlocking direction by unlawful behavior, the deforming operation of the deformation unit 4e does not allow an unlocking operation force to be transmitted to a locking/unlocking mechanism 6.</p> |
