Abstract:
1. A vehicle lamp comprising: a light source; a reflector whose first focal position lies in the vicinity of the light source, the reflector including a concave surface that reflects light from the light source frontward in an optical axis direction; a projection lens that is disposed so that its focal point lies in the vicinity of a second focal position of the reflector in front of the light source, the projection lens including a convex lens that focuses light from the reflector and that irradiates the light frontward; and a shutter that is disposed in the vicinity of the second focal position of the reflector, the shutter having an end edge that includes a rear end edge and a front end edge, the end edge forming a cutoff for light distribution, wherein the shutter is thickly formed so that the rear end edge is located substantially at a plane that is substantially perpendicular to the optical axis direction and contains the focal point of the projection lens, and the front end edge is positioned in front of the location of the focal point of the projection lens in the optical axis direction, the end edge of the shutter being slanted so that the shutter becomes lower towards the projection lens in relation to the optical axis direction of the vehicle lamp.
