Claims

[Scope of utility model registration request]

A cylinder body having a rotor insertion hole with a locking engagement groove on the inner peripheral surface, a key rotor rotatably provided in the rotor insertion hole of the cylinder body and having a key insertion hole, and a key difference between the key rotor. A lock plate insertion hole that is perpendicular to the insertion hole and has both ends penetrating the outer periphery of the key rotor, and a lock plate insertion hole that is slidably disposed in this lock plate insertion hole and moves in one direction by a spring member when the key is not inserted. A lock plate that is biased so that an engaging portion at an end engages with the lock engagement groove to prevent rotation of the key rotor, and a key insertion hole provided in the lock plate through which the key is passed. The key insertion hole is provided with an engaging protrusion that engages with a key thread provided in a groove on a side surface of the key at a substantially central position on the inner circumferential surface of the key insertion hole, and the key is inserted into the key insertion hole. When the key is not inserted into the key insertion hole, the portion of the engagement projection where the key thread engages is urged by the spring member to a position where there is no gap between the key insertion hole and the inner surface of the key insertion hole. When the key is inserted into the hole, the side edge of the key comes into contact with the key insertion hole of the lock plate, and the lock plate is moved against the spring member, so that the engaging protrusion is inserted into the key of the key. A cylinder lock characterized by being moved to a position where it can engage with the lock.
