<p>PROBLEM TO BE SOLVED: To shorten a length in forward/rearward direction by arranging an aiming screw tiling a lamp unit around a horizontal tilting axis which extends to the right and left direction of a U-shaped rod shaped part of a lamp housing between an horizontal ram of a lamp body of a lamp unit and a part facing opposite the horizontal ram in the upper and lower direction of the U-shaped lamp housing surrounding the arm. SOLUTION: A U-shaped lamp housing 20 which opens in the upper or lower direction in front view is shortened in its forward/rearward size surrounding a lamp body. An optical axis is controlled upward and downward by an aiming mechanism, including an aiming screw 50 controlling the inclination of a lamp unit U around a horizontal inclination axis Lx between pivotal supports P1, P2 at the upper portions of U-shaped rod parts of lamp housing. The aiming screw disposed upward/downward between a horizontal arm 40B, extending crosswise to the extending direction of lamp housing 20 at an upper portion on the back side of lamp body and an opposite horizontal stepped part 21 thereto, does not protrude rearward of the lamp unit U, so that in space saving is realized.</p> |
