The invention relates to an antitheft device for a motor vehicle steering column, comprising: a locking means mounted in a movable manner between an unlocked position in which it is intended to be disposed away from the steering column and a locked position in which it is intended to prevent said steering column from moving, anda cam (12) intended to rotate as one with a lock plug (5) in order to actuate the locking means depending on the position of the lock plug (5), characterized in that the cam (12) comprises: a nonreturn profile (13) intended to engage with a complementary assembly member (15) that is configured to prevent the cam (12) from rotating in the opposite direction once it has reached a predetermined angular position, and a push-locking recess (14) intended to receive a stop (20, 21) that is intended to engage with a complementary assembly member (15) that is configured to prevent the cam (12) from rotating in a predetermined direction of rotation from a predefined angular position and to allow rotation of the cam (12) by the lock plug (5) being pushed in beforehand.

A motor vehicle steering lock includes a housing in which is disposed a lock cylinder including a selector shaft which can assume various rotational positions. An adjustment element of an ignition switch is movably coupled to the selector shaft and triggers a desired function of the motor vehicle depending upon the rotational position of the selector shaft. The selector shaft and the adjustment element are connected for a conjoint rotation via an intermediate compensating element that allows for a movement of the selector shaft in relation to the adjustment element in a first axis direction oriented radial to a longitudinal axis of the selector shaft and a movement of the adjustment element in relation to the selector shaft in a second axis direction perpendicular to the first axis direction.

A lock for an antitheft device for a motor vehicle steering column is provided and includes a stator having a stator head with an opening, a rotor rotatably mounted about an axis with respect to the stator having an annular flange, a cam to rotate as one with the rotor, and an elastic element arranged between the cam and the rotor in order to exert a thrust load axially on the rotor. The opening of the stator is designed to engage with the annular flange to prevent the rotor from rotating in a predetermined rotation direction from a predetermined angular position and allows the rotor to rotate beyond the predetermined angular position by prior depression of the rotor.

A steering column assembly includes a jacket assembly and a bracket. The bracket has a first end portion defining a first opening and a second end portion defining a second opening. The second end portion overlaps the first end portion such that the second opening and the first opening are proximately aligned.

An object of the present invention is to provide an engine starting device which can prevent rattling of an ignition switch in a coupled state. Provided is an engine starting device including: a housing 2 accommodating a rotational operation shaft 1; and an ignition switch 3 coupled to the housing 2 and configured to be actuated upon application of rotational operation force to the rotational operation shaft 1. The ignition switch 3 is fitted and held in an attachment recess 4 formed in the housing 2, in such a way as to be prevented from falling from the attachment recess 4 by appropriate snap-locking portion 5. The peripheral wall surfaces of the ignition switch 3 and the attachment recess 4 on the fitting start end side and the peripheral wall surfaces thereof on the fitting finish end side come into pressure contact with each other substantially simultaneously with each other when the depth of the fitting of the ignition switch 3 to the attachment recess 4 reaches a predetermined depth, to thereby reduce rattling in the radial direction.

A steering lock device includes a trigger that is displaced as a frame cover drops from a frame, an auxiliary lock device that holds a lock member in a locked position as the trigger is displaced under condition that the lock member is positioned in the locked position, housing components that are arranged in a housing chamber defined by the frame cover and the frame or in a guide hole, and a trigger coupling member that couples the housed components and the trigger. When the housed components are displaced, the trigger is displaced via the trigger coupling member.

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 (4) that is provided with a cylindrical section (1) open at one end, and that houses a lock body (3) which moves in and out of a steering column as a result of the manipulation of a cylinder lock (2) secured in the cylindrical section (1); and a mounted member (6) that is mounted in a mounting hole (5), one end of which opens to the open end of the cylindrical section (1) and is formed in a cut-out shape. At both side ends of the mounting hole (5), to-be-locked sections (9) are provided that regulate the widthwise deformation of the mounting hole (5) by locking circumferentially with locking sections (8) of an inserted member (7) which is inserted into the cylindrical section (1) within the frame (4).

A steering shaft is rotatably provided inside an outer column and an inner column. A key lock collar is mounted on an outer peripheral surface of the steering shaft, the outer peripheral surface facing the outer column. The key lock collar includes a key lock collar body and a cylindrical portion. Multiple concave parts and convex parts extending in the axial direction are provided on an outer peripheral part of the key lock collar body along the circumferential direction. A lock key is engaged with the concave parts from adjacent to the outer column, and thus the rotation of the steering shaft with respect to the outer column is restricted. An outer diameter of the cylindrical portion is smaller than an outer diameter of the convex parts and larger than an outer diameter of the concave parts.
