Abstract

A cylinder lock device ( 1 ) includes: a rotor ( 30 ) rotatably disposed inside a cylindrical case body ( 20 ), a key insertion hole ( 31 ) being formed in the rotor ( 30 ) to axially extend; tumblers ( 50 ) provided in the rotor ( 30 ) to be axially movable, the tumblers ( 50 ) being radially urged outward to be engaged with a sleeve ( 40 ), the engagement of the tumblers ( 50 ) with the sleeve ( 40 ) being released when a normal key is inserted into a key insertion hole ( 31 ); slide members ( 70 ) for axially moving toward a lever member ( 60 ) side whenever the sleeve ( 40 ) relatively rotates by a predetermined angle with respect to the case body ( 20 ); a clutch member ( 80 ) disposed between the rotor ( 30 ) and the lever member ( 60 ), the clutch member ( 80 ) being provided in the lever member ( 60 ) to be axially movable; and an urgement member ( 90 ) for urging the clutch member ( 80 ) to a rotor ( 30 ) side so that the clutch member ( 80 ) is engaged with the rotor ( 30 ), in which when the slide members ( 70 ) move toward the lever member ( 60 ) side, the engagement of the clutch member ( 80 ) with the rotor ( 30 ) is released.

Description

technical field [0001] The present invention relates to a cylinder lock device, which is configured so that only a rotor and a sleeve can rotate relative to a casing when a foreign object such as an irregular key or a screwdriver is inserted. Background technique [0002] As a cylinder lock device used for a door of an automobile or the like, a rotor is known that is rotatably disposed inside a cylindrical housing and includes a key insertion hole formed so as to extend in the axial direction. In the cylinder lock device, a rotor is provided with a plurality of tumblers that can move freely in the radial direction, and each tumbler is pushed radially outward to engage with the sleeve. And, when the key is inserted into the key insertion hole, each tumbler is moved by the groove on the key. When a regular key is inserted, the engagement between each tumbler and the sleeve is released, and the rotor and the sleeve are independently rotatable. Then, when the key is rotated, t...
