According to the present invention, additional reflection surfaces 9UL, 9UR, 9DL, 9DR are provided for reflecting light L6 from semiconductor-type light sources 5U, 5D on intermediate invalid reflection surfaces 9, 9L, 9R. As a result, the present invention is capable of: reflecting the light L6 from the semiconductor-type light sources 5U, 5D on the intermediate invalid reflection surfaces 9, 9L, 9R, by means of the additional reflection surfaces 9UL, 9UR, 9DL, 9DR; illuminating the intermediate invalid reflection surfaces 9, 9L, 9R; and lessening a dark part.
