STEERING DEVICE

A steering device comprises: a rotary part provided in a manner allowing rotation about a rotary axis; a peripheral part arranged at a position farther from the rotary axis than the rotary part, and having a size in a direction of the rotary axis smaller than a size thereof in a direction of the rotation; and a light-emitting part provided at the rotary part. The light-emitting part includes: a light-emitting element; and a light-transmitting cover. The light-transmitting cover includes: a first surface where light from the light-emitting element is received; and a second surface on an opposite side to the first surface, and emitting the light received at the first surface toward the peripheral part. The light-transmitting cover includes: an inclined portion configured in such a manner that, as getting farther from the peripheral part along the second surface, the first surface gets closer to the second surface.
