Abstract
A leaf spring includes a plate having a hole into which a key cylinder is inserted, a notch into which a convex portion of the key cylinder is inserted, and spring tabs which can be bent elastically in the insertion direction of the key cylinder formed thereon. The top end of the spring tabs is inclined with respect to the bottom of the rectangular groove before bending, so that the top end is partially brought into contact with the back wall edge after bending. The key cylinder can be attached simply by inserting the key cylinder into the hole of an attachment unit. Freedom of the assembly order is therefore increased. Furthermore, the vibration of the key cylinder in the insertion direction of the key cylinder is reduced.
