Claims

[Claims for Utility Model Registration] (1) A key that is slidably disposed within a guide hole formed in a key cylinder and is fitted into an engagement hole formed in a key that is inserted into a key groove of the key cylinder. A cylinder lock comprising a locking member and an elastic member disposed in a blind hole formed in the locking member and pressing the locking member against the inside of a key cylinder, the locking member having a slit formed at an end thereof. , Fitting grooves are formed on the outer surface of the key cylinder on both sides of the guide hole on the same plane as the slit of the locking member, and both ends of the C-shaped ring are elastically attached to the fitting grooves, thereby increasing its own elasticity. A cylinder lock characterized in that a C-shaped ring is attached to a key cylinder, and a substantially central portion of the C-shaped ring is fitted into a slit of a locking member to serve as an abutting portion of an elastic member. (2) The cylinder lock according to claim (1), wherein both ends of the C-shaped ring abut against stopper portions formed on the key cylinder to prevent movement of the C-shaped ring in the circumferential direction. (3) A case having a housing hole formed in the length direction, a key cylinder arranged in the housing hole of the case and having a plurality of tumblers, and a key cylinder formed in the length direction approximately with respect to the key groove of the key cylinder. A guide hole formed in the key cylinder in the right angle direction, a locking member slidably disposed within the guide hole, and an elastic member disposed within the guide hole of the key cylinder that biases the locking member radially inward. The locking member is moved radially outward by a tool inserted into the keyway of the key cylinder and enters the locking hole formed in the case to prevent rotation of the key cylinder, and locks the key cylinder. When the key cylinder is inserted into a predetermined position, the locking member enters the locking hole formed in the key due to the elasticity of the elastic member and simultaneously separates from the locking hole in the case, causing the locking member to attach to the case. The key cylinder can be rotated without contact,
When the locking member protrudes radially outward from the key cylinder, the distance between the side surface of the outer end of the locking member and the inner wall of the locking hole in the case is equal to the distance formed between the side surface of the outer end of the tumbler and the case. For cylinder locks that are smaller than the distance from the inner wall of the tumbler groove, fitting grooves are formed on the outer surface of the key cylinder on both sides of the guide hole on the same plane as the slit of the locking member, and both ends of the C-shaped ring are fitted. The C-shaped ring is attached to the key cylinder by its own elasticity by being elastically attached to the groove, and the approximately center part of the C-shaped ring is fitted into the slit of the locking member to serve as the abutting part of the elastic member. Characteristic cylinder lock. (4) Claim (3) wherein bent portions that are engaged with recesses formed adjacent to the stopper portions at the ends of the fitting groove of the key cylinder are formed at both ends of the C-shaped ring.
