    摘要: A lighting unit cover including a deep color (first) resin layer subject to preblanking is laminated and molded in a predetermined position on a backside of a light color (second) resin layer on a surface side subject to postblanking. The second layer protrudes toward the first layer side and a boundary surface between the first and second layers and is offset by a distance toward the first layer side in a laminated portion. The first layer contacts the melted second resin and is subject to postblanking so that a part thereof is molten and drawn by its flow. A step portion in a cavity corresponding to a protruded portion of the second layer toward the first layer side blocks the flow of the molten first resin into the second layer. The first resin is not mixed into the first layer, resulting in excellent appearance and a large light emitting area.

    摘要: A vehicular lamp includes a vehicular component part that is molded by charging molten resin into a cavity defined by a first die that has a mirror surface-molding portion and a semi-gloss surface-molding portion and a second die that is movable relative to the first die and cooling the molten resin. The vehicular component part includes a mirror surface-formed portion having a mirror surface that is formed by the mirror surface-molding portion and a semi-gloss surface-formed portion having a semi-gloss surface that is formed by the semi-gloss surface-molding portion. A step surface is provided between the mirror surface and the semi-gloss surface of the vehicular component part. The semi-gloss surface-formed portion is protruded on a first die side relative to the mirror surface-formed portion.
