Claims

[Scope of utility model registration request]

a body, rotatably fitted into the body;
It has a key insertion hole at its axial center, and
a rotor having a plurality of tumbler insertion holes perpendicular to the key insertion hole; and a tumbler that is inserted into the tumbler insertion hole of the rotor and is urged by a spring to engage with a locking groove provided in the bottom. is disposed on the rotor, and at the rotor key attachment/detachment position, the key is urged by a spring and fitted into the cam groove of the body, and at the rotation position, the key is guided by the cam surface formed in the cam groove and inserted into the rotor. A cylinder lock having a sub-block tumbler that is retracted and engages with the key to restrict movement in the pulling direction, and has key threads on both left and right sides of the lock to allow the tumbler to detach from the locking groove against a spring. In a cylinder lock device comprising a main key and a sub-key in which a guide groove is formed, when the main key is operated, an engagement protrusion provided on the sub-lock tumbler engages with an engagement portion formed in the guide groove. The rotor can be rotated by engaging with the sub-lock tumbler and sinking into the rotor, while when the sub-key is operated, the engaging protrusion is locked in the guide groove, preventing the sub-lock tumbler from sinking into the rotor. A cylinder locking device characterized in that a rotor is prevented from rotating by being blocked.
