A steering device includes: a steering shaft which extends along a central axis and to which a steering wheel is coupled on one side in an axial direction; a tubular steering column which is disposed on an outer circumferential side of the steering shaft and extends in the axial direction; and a gearbox which is disposed on the other side in the axial direction of the steering column and is fixed to the steering column. The steering column includes a fixing member provided at an end on the other side in the axial direction and fixed to the gearbox, and an outer circumferential surface on one side in the axial direction of the fixing member has an outer diameter which increases toward the other side in the axial direction.

Steering device

A steering device includes a cylindrical steering column that extends in an axial direction. The steering column includes: an upper column; a lower column; and a fixing member. The fixing member includes a cylindrical part, and the cylindrical part includes: a small diameter part that is fitted to the lower column; a curved part that has an outer circumferential surface whose outer diameter increases toward the other side in the axial direction; and a large diameter part whose outer diameter is larger than an outer diameter of the small diameter part.
