<p>PURPOSE:To prevent steering from being easily operated even if a steering lock condition is repeatedly released by preventing breakdown of a lock holder when a steering shaft is rotated by excessive force. CONSTITUTION:In a lock bar 11, breaking grooves 16,... having the same shape are arranged in a plurality with every prescribed interval (a length of A) from the left end, and projections 17,... are arranged in the same degree with the number of breaking grooves 16 at the same interval A with these breaking grooves 16. These breaking grooves 16 are constituted so as to be cut in the case where prescribed rotational torque is applied to the lock bar 11 from a lock holder 13 when all are put in a steering lock condition. Thereby, the lock holder 13 is prevented from being broken down. Since the lock bar 11 is again inserted in an engaging groove 14, the possibility of easy steering operation is prevented.</p> |
