A lens includes an incident surface through which outgoing light enters the lens, the incident surface being formed at a portion opposed to a light source, and an emission surface through which incident light incident on the incident surface exits from the lens. The incident surface refracts outgoing light in a direction away from an optical axis of outgoing light, along a direction orthogonal to the optical axis. The emission surface refracts incident light in a direction away from a centerline of incident light, along a direction orthogonal to the centerline.

A structure for fixing a light guiding member includes a light guiding member that guides light emitted from a light source to a prescribed position, a holder that holds the light guiding member, and a fixed member fixed to the light guiding member. The holder includes an insertion hole through which the light guiding member is inserted. The light guiding member includes a flange larger in outer geometry than the insertion hole and a shaft portion connected to the flange and inserted through the insertion hole. The fixed member is fixed to a portion of the shaft portion that projects from the insertion hole and larger in outer geometry than the insertion hole.

A water shut-off structure includes a member and a holder that holds the member. The holder includes an insertion hole through which the member is inserted. The member includes a flange larger in outer geometry than the insertion hole and a shaft portion connected to the flange and inserted through the insertion hole. The holder includes a flange receiving portion that receives the flange. The flange receiving portion includes an annular rib in a shape surrounding the entire circumference of the insertion hole and projecting toward the flange.
