1. A steering device comprising:
a steering shaft that extends along a central axis and is connected on one side in an axial direction thereof to a steering wheel;
a cylindrical steering column that is disposed on an outer circumferential side of the steering shaft and extends in the axial direction; and
a gear box that is disposed on the other side in the axial direction of the steering column and fixed to the steering column, wherein
the steering column includes:
an upper column;
a lower column that is disposed on the other side in the axial direction of the upper column and partially fitted to an inner circumferential side of the upper column; and
a fixing member that is provided on the other side in the axial direction of the lower column and fixed to the gear box,
the fixing member includes a cylindrical part that extends in the axial direction,
the cylindrical part includes:
a small diameter part that is fitted to an inner circumferential side of the lower column;
a curved part that is adjacent to the other side in the axial direction of the small diameter part and has an outer circumferential surface whose outer diameter increases toward the other side in the axial direction thereof; and
a large diameter part that is adjacent to the other side in the axial direction of the curved part and has an outer diameter larger than the outer diameter of the small diameter part,
in a cross section including the central axis, the outer circumferential surface of the curved part is an arc, and
the outer diameter of the large diameter part is smaller than an outer diameter of the lower column.
