車両用灯具。[Scope of Claim for Utility Model Registration] A vehicle lamp in which an outer lens is attached to cover a front opening of a lamp housing, and a light source bulb is disposed within the lamp housing, wherein an inner lens is provided between the outer lens and the light source bulb. A surface is provided in the peripheral part of the inner lens to reflect light that has passed through the inner lens from near the center of the inner lens to the peripheral part, and reflects the light toward the outer lens. A concave portion having a step-like surface is formed in the front surface of the central portion of the lens, and the step-like surface (a) totally reflects the direct light coming from the light source bulb toward the reflective surface in the peripheral portion; (b) a surface substantially perpendicular to the optical axis that passes direct light from the light source bulb toward the outer lens;
