徴とする請求項１記載の車両用灯具。[Claims for Utility Model Registration] (1) An inner lens consisting of an outer lens fixed in front of a lighting bulb provided on the front side of a reflector, and a double-reflection prism carved between the outer lens and the lighting bulb. In the vehicle lamp equipped with the above-mentioned inner lens, a large number of prisms are engraved on the side surface of the outer lens in parallel or concentric circles at a constant pitch, and the basic shape of the lens is oriented toward the vapor deposition source side for mirror finishing. The inner lens has a concave curved surface, and the intersection point of the lens axis including the vapor deposition source and a line extending the non-evaporation surface of each of the prisms is located far from the vapor deposition source. 1. A vehicular lamp characterized in that a light focusing step is engraved on the side surface of the bulb at the same pitch as the prism. (2) The vehicle lamp according to claim 1, wherein the pitch between the prism of the inner lens and the condensing step is 1.5 mm to 3.0 mm.
