ABSTRACT:
A device for locking the steering shaft of a motor vehicle against rotation by means of a locking bolt cooperating with locking recesses of the steering shaft. A control member that can be rotated back and forth displaces the locking bolt back and forth radially relative to the axis of rotation of the control member between a locking position and a release position. The locking bolt has a laterally protruding pin that engages a spiral groove of the control member on the front face of the control member adjacent to the locking bolt and that winds about the axis of rotation of the control member. The locking bolt has a pin which is is spring-loaded and movable in the direction towards the control member. The control member can be rotated as far as into the position corresponding to the locking position of the locking bolt even if no locking recess of the steering shaft is located in front of the locking bolt to receive same.
