IPC: B60R25/023
Filed: 2001-09-05
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive steering lock device which is not broken even by an excessive torque. SOLUTION: The steering lock device 9 has a spacer 11 between a steering shaft 3 and an annular collar 10 which is externally fitted thereto in a relatively turnable manner.
