Abstract: A steering apparatus (1) is provided, which includes: a key lock collar (5) being fitted on a steering shaft (2) and restricted from rotating by a steering lock mechanism when performing a steering lock; and a slip ring (8) being interposed between the steering shaft (2) and the key lock collar (5) in radial directions, wherein the slip ring (8) includes a plurality of protruded portions (9) protruding outwardly or inwardly in the radial directions and being provided in a circumferential direction, and an inner peripheral portion of the key lock collar (5) covering the slip ring (8) is formed with large-diameter portions (7a) and small-diameter portions (7b) in the axial direction, thereby further stabilizing slip torque of the key lock and enlarging a range of dimensional allowance.

Abstract: 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.
