ABSTRACT:
A tilt steering apparatus comprises a lock lever rotatable around the axis of a supporting shaft. When a lock lever is rotated around the axis of the supporting shaft, a cam surface is rotated relative to a cam follower. As a result, the cam surface presses the cam follower against side plates of a fixed bracket, thereby achieving tilt locking. The cam surface has a plurality of slopes corresponding to a rotation stroke position of the lock lever. The operating torque of the lock lever at the time of a locking operation is reduced without increasing the range of the operating angle of the lock lever.
