Claims

[Scope of utility model registration request]

For vehicles in which a reflector consisting of a paraboloid of rotation, a lens attached to the front opening of the reflector, and a light source filament stretched between internal lead wires are arranged in a lamp chamber partitioned by the reflector and the lens. A lens for a vehicle lamp used in a lamp, the lens has a Fresnel lens-like prism in a small area (which corresponds to the area where the light from the light source filament projects the shadow of the internal lead wire onto the reflecting mirror). A lens for a vehicle lamp, characterized in that a step portion is formed, and a diffusive step lip having diffusivity in approximately one direction is provided in front of the prism step portion.
