    • A lamp for a vehicle having a metallic light shielding shade that comprises a shade body serving as a light shielding section and a leg which extends rearward from the shade body in substantially a horizontal direction so that the light shielding section supported in a cantilever manner when the rear end of the leg is inserted and secured to a leg insertion hole formed in a reflector of the lamp, wherein the leg of the light shielding shade is obtained by laminating two plate-like extending portions that have expanded portions; and holding grooves are formed in the leg insertion hole. When the expanded portions are press-fitted into the holding grooves from the front side of the reflector, the leg is inserted in the leg insertion hole, and the rear end of the extending leg is bent so as to be on the rear surface of the reflector; as a result, the leg of the light shielding shade is securely held in the leg insertion hole of the reflector. The leg is formed by laminating two plate-like extending portions so as to have a high rigidity, realizes excellent light distributing characteristics, and prevents deflection of light distribution.
    • 一种具有金属遮光罩的车辆灯,包括用作遮光部的遮光体和从荫罩体的大致水平方向向后延伸的支腿,使得遮光部以悬臂方式支撑时 腿的后端插入并固定到形成在灯的反射器中的腿插入孔,其中遮光罩的腿通过层叠具有展开部分的两个板状延伸部分而获得; 并且在腿部插入孔中形成有保持槽。 当膨胀部分从反射器的前侧压配合到保持槽中时,腿部插入到腿部插入孔中,并且延伸腿的后端被弯曲成位于 反射器 结果,遮光罩的腿被牢固地保持在反射器的腿部插入孔中。 该腿通过层压两个板状延伸部分以具有高刚性而形成,实现优异的光分布特性,并且防止光分布的偏移。
