  • Patent number: 7412858
    Abstract: There are provided a cam plate (5) that rotates in an unlocking direction and a locking direction, and a locking shaft (8) that moves between a locking position where rotation of a steering shaft is prevented and an unlocking position where the rotation of the steering shaft is permitted by rotation of the cam plate (5). The cam plate (5) is provided with a steering lock preventing unit (20) through a spring (22). The steering lock preventing unit (20) holds the locking shaft (8) in the unlocking position. A ball (23) moves on a moving surface (24) of a motor unit (4) opposed to the cam plate (5) by rotation of the cam plate (5). A projecting wall (25) is provided on the moving surface (24) at a position before the unlocking position in a range where the ball (23) moves from the locking position to the unlocking position.
