Claims (1)

[Claims for Utility Model Registration] By blocking the rotation of the cylinder lock during the return rotation to the lock position and performing another operation to release the block, the cylinder lock can be returned to the lock position. In a steering lock device equipped with such a safety mechanism, a cylinder of a cylinder lock is supported so as to be movable in a key pushing direction at least in a return rotation prevention position and is biased in a key pulling direction, and an outer periphery of the cylinder. a stopper member disposed in the cylinder, supported so as to be movable over a certain range in the axial direction of the cylinder, and biased in the key pushing direction; and a stopper member protruding in the key pulling direction so as to move and rotate together with the cylinder. and a unidirectional locking portion, wherein the unidirectional locking portion is engaged with the tip of the stopper member at the return rotation blocking position when rotating back to the lock position, and the unidirectional locking portion is rotated back. By pressing the key at the return rotation prevention position and moving the cylinder, the cylinder moves to a position where it does not engage with the stopper member, releases the engagement with the stopper member, and moves from the lock position to the on position. A steering lock device with a safety mechanism, which is formed so that when the cylinder rotates, a stopper member is pushed against an urging force to enable rotation of the cylinder.
