摘要

A projector capable of preventing a light tunnel from positional deviation is obtained. This projector comprises a rectangular light tunnel having a hollow light guide path capable of passing light therethrough for shaping the light with the light guide path, an optical component holding member provided with a holding portion holding the light tunnel and a light tunnel clip including a first pressing portion and a second pressing portion pressing first and second surfaces, adjacent to each other, of the light tunnel toward the holding portion of the optical component holding member for holding the light tunnel in a pressed state, while the first pressing portion and the second pressing portion press positions of the first and second surfaces of the light tunnel located substantially on the same line perpendicular to the traveling direction of the light respectively.
