Steering column assembly

摘要

A steering column assembly includes a support bracket provided with a pair of side plates, a lower jacket provided with a pair of jacket side plates and pivotally coupled with the support bracket swingably about a tilt axis, an upper jacket provided with a support flange coupled with the lower jacket slidable between the pair of the jacket side plates in a telescopic direction, spacers disposed between the support flange and the pair of the jacket side plates, respectively, and a lock mechanism including a lock bolt. The lock mechanism fastens, by the lock bolt, the pair of the side plates of the support bracket to press and fix the pair of jacket side plates of the lower jacket, and to press and fix the support flange of the upper jacket via the spacers.
