A stationary tooth row (80) is provided in a restricted member that is not displaced together with a steering wheel during tilt adjustment of a steering system. A movable tooth row (90) is provided in a movable member that is displaced in a tilt direction (Y) together with the steering wheel during tilt adjustment. The movable tooth row (90) includes a first movable tooth (91) and second movable teeth (92). A first curvature radius (R1) of a tooth tip of the first movable tooth (91) is made smaller than a second curvature radius (R2) of a tooth tip of each of the second movable teeth (92) to make a tooth depth of the first movable tooth (91) greater than a tooth depth of each of the second movable teeth (92). |
