PROBLEM TO BE SOLVED: To solve a problem of a conventional lamp for a vehicle that performance is not sufficient because of a low efficiency against a light source and that an appearance can not be improved more because of a poor freedom in shape. SOLUTION: In a lamp for a vehicle 1, a lower part of the first reflection surface 3 having a long axis in an irradiation axis direction against a light source 2 is cut off, and a pair of second reflection surface 6 having a long axis in right and left horizontal directions is provided on the cut off part, and light is supplied to the third reflection surface 7 provided at left and right of the first reflection surface 3. Efficiency is improved by utilizing nearly all of light emitted from the light source 2 as irradiation light and a shape becomes novel by three reflection surfaces 3, 6 lining in a lateral direction. |
