PROBLEM TO BE SOLVED: To provide a required light distribution pattern with a horizontal diffusion lens step formed on a lens in a fog lamp having a downward curve at a portion near the outer end section of the lens in the car width direction arranged laterally inclinatorily in the front of a reflecting mirror and fed with the reflected light from the oblique rear to the portion. SOLUTION: A horizontal diffusion lens step 50A formed at a portion near the outer end section 12b of a lens 12 in the car width direction in a horizontal diffusion lens step 50 is formed so that the lens 1 is seen curved and displaced inward in the car width direction while its lateral width is narrowed from the above to the below when it is seen from the front of a lighting fixture, not seen extended in the vertical direction like the horizontal diffusion lens step at other portions. The horizontal diffusion lens step 50A can be extended in the vertical direction when it is seen from the incident direction of the reflected light, the reflected light to the horizontal diffusion lens step 50A is transmitted and diffused without being inclined against the horizontal direction, and a horizontal diffusion pattern can be formed. |
