<p>PURPOSE: To prevent a burglary by providing an inclined surface to the axial direction of the steering shaft, in order to move a receiver member in the axial direction by the function of the torque more than a specific value, and providing an auxiliary lock member to the receiver member which is displaced by the movement in the axial direction. CONSTITUTION: A quilling 11 moves in the axial direction and engaged to an auxiliary ring 41 through teeth 11c and 41c. In this case, since the quilling 11 is engaged to a key 13 through a side surface 11a in the axial direction of a key groove 11 a, it is guided to the engaging position with the auxiliary ring 41 securely. Since the auxiliary ring 41 is supported to the car body side through columns 2, the rotating operation of a steering wheel 5 is blocked in two stages by the key 13, and the anti-theft effect can be improved.</p> |
