A rear structure of a vehicle includes a lamp and a dividing member. The lamp includes at least one lamp part, and is disposed on a rear portion of the vehicle. The dividing member is a member for dividing the lamp at least in a vehicle up-down direction. The dividing member is formed in such a manner that blinking of a single lamp part of the lamp is directly viewable both from above and below the dividing member when viewed from the rear side of the vehicle.

A light-transmitting member is arranged such that light emitted from a light guide enters. Light which enters an incident end surface is emitted from an emitting end surface. The light-transmitting member has a wide width portion and a narrow width portion. A width of the incident end surface of the wide width portion is larger than a width of the light guide in a direction perpendicular to a longitudinal direction of the light guide. A width of the incident end surface of the narrow width portion is smaller than the width of the incident end surface of the wide width portion. The incident end surface has a curved surface convex toward the light guide at least in the wide width portion. A curvature of the incident end surface in the wide width portion is greater than a curvature of the incident end surface in the narrow width portion.
