ABSTRACT:
A lock device includes: a case member that is attached to a lock target; a sleeve member that is housed inside the case member such that the sleeve member is movable along an axial direction; a plunger member that is housed inside the sleeve member such that the plunger member is movable along the axial direction; a coupling structure in which a key insertion hole that allows insertion of a key is formed, the coupling structure being placed inside the plunger member and coupling together the sleeve member and the plunger member; and a manipulable member that is rotatably coupled to the sleeve member and the plunger member, rotates when just the plunger member moves, and releases the locked state of the lock target. The coupling structure is configured to release the coupling just when a regular key is inserted into the key insertion hole.
