Steering apparatus

A steering apparatus capable of adjusting a position of a steering wheel by moving a column that holds a shaft of the steering wheel relative to a vehicle body, the steering apparatus comprising:

• a turning lever for locking and unlocking the column relative to the vehicle body;
• a cam that converts a turning movement of the turning lever into a movement in an axial direction of the turning movement, thereby locking and unlocking the column;
• and
• a sleeve that holds the cam and slides with respect to the cam when the turning lever turns, wherein:
• grease is applied to a sliding surface between the sleeve and the cam;
• the cam includes a moving cam that rotates together with the turning lever and a fixed cam that moves in the axial direction due to the rotation of the moving cam;
• the sleeve slides with respect to the moving cam and the grease is applied to a sliding surface between the sleeve and the moving cam;
• and
• the sleeve is rotationally movable, but is fixed axially, relative to the moving cam while the sleeve is axially movable, but is fixed rotationally, relative to the fixed cam.

• and
• the sleeve is fixed both axially and rotationally relative to the fixed cam while the sleeve is movable both axially and rotationally relative to the moving cam.
