description An optical path cover is located on an optical path through which beam light travels. The optical path cover includes a cylindrical portion through which the beam light is capable of passing. A plurality of protruding portions are formed on inner walls of the cylindrical portion, the inner walls facing toward a side of an optical axis of the beam light. The protruding portions, each of which has a convex shape in cross-section taken perpendicularly to the optical axis, are arranged next to each other with the convex shape facing toward the side of the optical axis. Each of the protruding portions has an elongated shape extending along the optical axis.
