The purpose of the present invention is to provide a steering lock device that can prevent improper access to a cylinder lock due to the deformation of a mounting hole formed in a cut-out shape. The steering lock device comprises: a frame () that is provided with a cylindrical section () open at one end, and that houses a lock body () which moves in and out of a steering column as a result of the manipulation of a cylinder lock () secured in the cylindrical section (); and a mounted member () that is mounted in a mounting hole (), one end of which opens to the open end of the cylindrical section () and is formed in a cut-out shape. At both side ends of the mounting hole (), to-be-locked sections () are provided that regulate the widthwise deformation of the mounting hole () by locking circumferentially with locking sections () of an inserted member () which is inserted into the cylindrical section () within the frame ().

A door handle device is provided with: a door handleby which the door of a vehicle can be opened and closed; a mounting bracketfor supporting the door handlethrough a supporting shaftso that the door handle can be swung in the back-and-forth direction with respect to the doorof the vehicle; and a switch unit, which is arranged between the door handleand the mounting bracket, which generates an electric signal for locking and unlocking a door lock provided in the door of the vehicle. A contact portion (an engaging groove), with which the supporting shaftcomes into contact, is formed in the switch unit. When the supporting shaftis inserted into a handle shaft insertion holeand a bracket shaft insertion holeso that the supporting shaftcan be engaged with the holes by an engaging grove, the switch unit is fixed to the mounting bracket.

A casing of a cylinder lock device comprises two pieces of a rear casing for receiving a rotor and a front casing for receiving a key cylinder and a housing . The key cylinder and a rotor axially move and rotate upon insertion of a proper key into the key cylinder and subsequent rotation of the key . In assemblage of the cylinder lock device, the rotor and key cylinder are connected by a joint means of non-circular section for their integral rotation, and the rotor is connected to the housing by a connecting means for their integral rotation and axial movement. The front casing can detachably be connected to the rear casing by the coupling means
