Title:
STEERING COLUMN DEVICE
Document Type and Number:
Japanese Patent JP2008302751
Kind Code:
A
Abstract:

To provide a steering column device capable of suppressing the eccentric contact of an outer column and an inner column at a low cost.

Since the inner circumferential surface of the outer column 3A has a plurality of protrusions, that is, raised portions 3e abutting on the outer circumferential surface of the inner column 3B, it is sufficient to accurately form only abutting surfaces of the plurality of raised portions 3e. Therefore, a manufacturing cost can be suppressed, and the outer column 3A and the inner column 3B can abut on each other along the circumferential direction with favorable balance.
