Claims

[Scope of utility model registration request]

A large-diameter inner circumferential surface and an engaging protrusion protruding from the large-diameter inner circumferential surface are provided at the end of a cylinder case having a plurality of driver pin holes, and one side of a flanged ring is fitted into the large-diameter inner circumferential surface. a notch recess that engages with the engagement protrusion, a retaining protrusion protruding from the outer peripheral surface of the other side of the flanged ring, and a notch formed at the end;
A plug having a tumbler pin hole that is fitted into the cylinder case and communicates with the driver pin is provided with a small diameter outer circumferential surface that is fitted into the flanged ring, and a cam that loosely fits into the notch at the end of the small diameter outer circumferential surface. and a locking rod is fixed, a master pin hole is provided in the flanged ring that can communicate with the tumbler pin hole and the driver pin hole, the master pin is inserted into the master pin hole, and the tumbler pin inserted into the tumbler pin hole is inserted into the tumbler pin hole. A cylinder lock that also serves as a master key and child key, in which the contact surface between the master pin and the driver pin, which are pushed by the tumbler pin when pushed by the master key, matches the outer circumferential surface of the flange ring; 1. A locking device comprising a main body having a hole for inserting a case into the case, and a groove formed in the inner circumferential surface of the hole through which the locking protrusion can be inserted.
