ABSTRACT:
An anti-theft device for locking the steering of an automobile vehicle comprises a crown gear (3) which is rotatable with the steering shaft (1) and has teeth (8) separated by concave sections having a part-circular profile (9), and a locking element on a spindle positioned parallel to the steering shaft (1) and rotatable by a lock (17), the locking element comprising a finger (10) having a length substantially equal to the radius of the concave sections (9) of the crown gear (3) and an outer part-circular face (14) of the same radius as the concave sections (9). The face of the locking finger engages a concave section to prevent rotation of the crown gear and steering shaft in the locked position and the finger is completely out of engagement with the concave sections and gear teeth to allow rotation of the crown gear and steering shaft when in the unlocked position.
