PROBLEM TO BE SOLVED: To permit an observer to get a clear impression in either case of moving a viewpoint into right or left as well as top or bottom, i.e., any directions after securing the transparency of a lamp fixture in an indicating lamp for vehicle. SOLUTION: It is constituted by dividing a reflecting surface 14a of a reflector 14 into a plurality of segments S in the form of righting lattices and assigning reflecting elements 14s1, 14s2 to them, respectively. Then, it forms the reflecting surface 14a as waveform surface of both directions alternatively repeating the reflecting element 14s1 on a hollow surface and the reflecting element 14s2 on a convex surface against any directions of the both directions conforming to the crossing lattices. With this, in the case of viewing the reflecting surface 14a of the lamp fixture in the front, when moving viewpoint toward right and left as well as from top to bottom, it dynamically changes the brightness pattern of the reflecting surface 14a in accordance with the viewpoint movement and gives a strongly sparkling feeling to an observer. |
