摘要:
A lamp unit of a vehicle lamp includes a projection lens arranged on an optical axis extending in the longitudinal direction of a vehicle, a light-emitting element arranged so as to face upward behind a rear focal point of the projection lens and in the vicinity of the optical axis, and a reflector arranged so as to cover the light-emitting element from above and to reflect the light from the light-emitting element forward toward the optical axis. A mirror member is provided between the reflector and the projection lens. The mirror member includes an upward reflecting surface that upward reflects a portion of the reflected light from the reflector, and a front end edge formed so as to pass through the rear focal point of the projection lens. A region of the upward reflecting surface located nearer a self-lane side than the optical axis is constituted with a horizontal plane including the optical axis. A shielding projection that shields the reflected light from the reflector deflected by the horizontal plane is formed in a position of the horizontal plane that is apart from the front end edge of the upward reflecting surface to a rear side.
