Claims

[Scope of utility model registration request]

A key device comprising a cylinder lock in which a tumbler that protrudes and retracts from the outer circumferential surface of the rotor engages and disengages from an engagement groove on the inner circumferential surface of the cylinder, and a key plate that draws the tumbler into the rotor when inserted into the cylinder lock, There are seven types of tumblers, and the maximum height difference between adjacent tumblers is 1.
A key device characterized in that operability when inserting a key plate is improved by limiting the length to 0.05 mm.
