摘要： A steering shaft 11 is rotatably provided inside an outer column 5 and an inner column 7. A key lock collar 15 is mounted on an outer peripheral surface of the steering shaft 11, the outer peripheral surface facing the outer column 5. The key lock collar 15 includes a key lock collar body 19 and a cylindrical portion 21. Multiple concave parts 19a and convex parts 19b extending in the axial direction are provided on an outer peripheral part of the key lock collar body 19 along the circumferential direction. A lock key 17 is engaged with the concave parts 19a from adjacent to the outer column 5, and thus the rotation of the steering shaft 11 with respect to the outer column 5 is restricted. An outer diameter D1 of the cylindrical portion 21 is smaller than an outer diameter D2 of the convex parts 19b and larger than an outer diameter D3 of the concave parts 19a.
