Claims

[Claims for Utility Model Registration] (1) A cylindrical steering column, a steering shaft that is inserted through the steering column and rotates inside the steering column based on operation of the steering wheel, and an outer periphery of the steering column. As the key of the ignition switch provided on the surface of the ignition switch can be removed, a lock pin elastically protrudes inside the steering column, and the lock pin is formed in a portion fixed to the steering shaft. In the steering lock device, the lock pin is formed into a substantially cylindrical shape by press-forming a metal plate, and the inner end of the lock pin is partially engageable. What is claimed is: 1. A steering lock device characterized in that a lock bracket having an engaging hole formed therein is welded and fixed to the outer peripheral surface of an intermediate portion of a steering shaft. (2) The lock bracket includes a pair of small-diameter arcuate portions having an inner diameter matching the outer diameter of the steering shaft, a large-diameter arcuate portion having an inner diameter larger than the outer diameter of the steering shaft, and the large-diameter arcuate portion. and an inclined part that connects both ends of the small diameter circular arc part with one end of the pair of small diameter circular arc parts, and is formed into a substantially cylindrical shape by abutting the other ends of the small diameter circular arc parts against each other, and the lock pin is attached to the large diameter circular part. 2. The steering lock device according to claim 1, further comprising an engagement hole with which an inner end of the steering lock can be freely engaged. (3) The steering lock device according to claim 2, wherein the width in the axial direction of the large-diameter arcuate portion constituting the lock bracket is larger than the width in the axial direction of the small-diameter arcuate portion. (4) The steering lock device according to claim 2 or 3, wherein the edge of the small diameter arc portion is welded to the outer peripheral surface of the steering shaft.
