ABSTRACT:
A steering shaft locking device has a locking rotor rotatably mounted in a housing which is key actuated. A movable piece is moved radially outwardly of the rotor when a key is inserted therein, but is free to move inwardly when no key is present. A cam on the end of the rotor moves a lock bar transversely of the rotor against the action of a first spring. A projection on the edge of the lock bar engages one end of a lock shaft for moving it in one rotational direction from a neutral position, at which it is held by a second spring which is weaker than the first spring, and the other end of the lock shaft has a shape such that when it is moved in the one rotational direction, it moves away from the movable piece, and when it is moved in the other direction by the movement of the lock shaft by the first spring, it moves the movable piece, and thus permits the lock bar to move past the one end of the lock shaft.
