STEERING APPARATUS |
| 摘要 |
A steering apparatus includes a key lock collar (5) fitted on a steering shaft (2) and restricted from rotating by a steering lock mechanism when performing a steering lock, and a cylindrical slip ring (7) interposed between the steering shaft (2) and the key lock collar (5) in radial directions. The slip ring (7) includes a plurality of protruded portions (8) protruding outwardly or inwardly in the radial directions and being provided in a circumferential direction, and an axis-directional portion of the steering shaft (2) covered by the slip ring (7) is formed with a large-diameter portion (10a) and a small-diameter portion (10b), thereby further stabilizing slip torque of the key lock collar (5) and enlarging a range of a dimensional allowance. |
