Abstract
A lock device () is used with a flat key (K) having asymmetric opposite edges (). The lock device () includes a key rotor () which is configured to have distances from a central axis line (O) of the key (K) to abutment points of the edges () against the tumbler (-) respectively, and the distances are set so as to equal each other such that the non-reversible key is capable of reversible use in an inserted state of the key (K) into a key insertion hole ().
