Patent ID: 7823427

Claim:
A cylinder lock device comprising: a first body in cylindrical shape; a rotor arranged to be rotatable inside the first body including a key insert hole to which a key is inserted, the key insert hole being formed to extend in an axial direction; a first sleeve arranged to be rotatable between the first body and the rotor; a second sleeve arranged to be rotatable between the first body and the rotor, and disposed more distant than the key insert hole; a tumbler provided in the rotor to be movable in a radial direction to engage with the first sleeve or the second sleeve when biased to an outer radial direction and disengage with the first sleeve or the second sleeve when a regular key is inserted into the key insert hole; a lever member arranged to be rotatable and facing to a key insert hole side in the rotor, for locking or unlocking a vehicle; a first slide member arranged between the first sleeve and the first body, for moving in an axial direction toward the lever member each time the first sleeve rotates relatively to the first body at a predetermined angle; a second body in a cylindrical shape arranged between the first and second sleeve, a lock part for making the second body rotatably movable or immovable with respect to the first body; a second slide member arranged between the second sleeve and the second body, the second slide member moving in the axial direction toward the lever member each time the second sleeve rotates relatively to the second body at a predetermined angle; a clutch member arranged between the rotor and the lever member to be movable in the axial direction in the lever member, and allowed to engage or disengage with the rotor; and a biasing member to bias the clutch member toward the rotor to be engaged with the rotor.
