Claims

[Scope of utility model registration request]

A keyhole 3 is provided in the center of a rotor 2 rotatably housed in a case 1 in the axial direction, and a slot 6 in which a disk tumbler 4 and a biasing spring 5 are housed is passed through the rotor 2 in a transverse direction. The key thread 8 of the plate key 7 inserted into the key hole 3 is used to open the through hole 9 of the disc tumbler 4.
When the hole edge surface 9a of the disk tumbler 4 is pressed,
Relief groove 10 into which the regulating protrusion 4a at the base end of the
is provided on the inner peripheral surface of the rotor 1, and a plate key 7 is inserted from the key hole 3.
A locking groove 11 is provided on the inner peripheral surface of the rotor 1, with which the locking projection 4b at the tip of the disc tumbler 4 engages when the disc tumbler 4 is removed. The cylinder lock is provided protruding from one half of the same side with respect to the line, and the width dimension of the relief groove 10 corresponds to the horizontal width of the regulating projection 4a, and the width dimension of the locking groove 11 corresponds to the horizontal width of the locking projection 4b.
