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,

Abstract: A device for locking a steering mechanism which includes a key rotor rotatable and axially movable in a cylinder, a rotatable lock cam coupled to the key rotor to control a lock member adapted to lock and unlock the steering mechanism, a movable regulating plate in the lock cam normally protruding perpendicularly therefrom to prevent the lock cam from turning from an unlock position to a lock position and a drive cam for moving the regulating plate when the key rotor is pushed in so as to allow the lock cam to turn to the lock position.
