<p>Disclosed is a lock device (10) in which a planar key (K) having opposite side portions is used, wherein the key (K) has asymmetric teeth (3, 4) between one side portion and the other side portion. The lock device (10) comprises a key rotor (14), wherein even if the key (K) is inserted into a key insertion hole (23) in a normal state or a reversed state, while the key (K) is inserted in the key insertion hole (23), distances from the central axis (O2) of the key (K) to abutting points between the teeth (3, 4) and tumblers (32a to 32c) are set to an identical distance (L), so that the non-reversible type key (K) can be used as a reversible type.</p> |
