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. , a cylinder lock comprising an internal key having a guiding groove with a key thread on both left and right sides of the lock to allow the tumbler to detach from the locking groove against the spring; A sub-lock tumbler is disposed, which is pushed by a spring and fitted into a cam groove of the body at the key attachment/detachment position, and which can be inserted into the rotor by being guided by a cam surface formed in the cam groove at the rotation position; When the sub-lock tumbler is inserted into the cam groove, it does not engage with the key, and when it is inserted into the rotor, it engages with an engaging portion formed in the guide groove of the key and moves in the key removal direction. A cylinder lock characterized by having an engaging protrusion that restricts movement of the cylinder lock.
