Abstract

PROBLEM TO BE SOLVED: To provide a lock device using a magnet capable of preventing a key from being pulled out while a lock is operated and allowing a user to learn that the key reaches a lock close position or a lock open position securely. SOLUTION: This lock device 10 consists of a slider 20 moving together with the key using the magnet, a slider cover 30, a stopper 40 locking a hook 50 in the interlocking relationship with the slider 20 for lock operation, a push 60 operating the hook 50 when the lock is opened, a main body 70 on an outermost side, and a back plate 75 (shown by a two-dot chain line). The hook 50 locks a knob of, for example, a zipper opening and closing a lid of a bag. A click pin is provided on the slider 20 to engage its head part with a recessed and projecting parts 76 provided on the back plate 75. When the key and the slider reach the lock close position or the lock open position at both ends, the head part of the click pin enters the recessed part to generate a click sound. Moreover, while it is in an intermediate section and moves, it is engaged with the projecting part, and a tip of the click pin enters a hole of the key to prevent the key from being pulled out.
