A vehicle lampcomprises a light source portionand a plastic decorative memberin a lamp chamberconstituted by a bodyand a lamp coverfor covering the front of the body. The decorative member has a skin layerand a core layerwhich are formed by sandwich molding; and the core layer is located in at least a portion that requires heat-resistance in the decorative member and formed of resin material greater in heat-resistance than resin material for the skin layer.

A lamp reflector having a substrate in which desired surface smoothness and rigidity are ensured, while the dimensional accuracy is high. Also, a method of manufacturing such a lamp reflector. In order to ensure surface smoothness, rigidity, and high dimensional accuracy, the lamp reflector is provided with a substrate made of a composition containing at least polyphenylene sulfide resin (PPS resin), synthetic calcium carbonate whiskers, and synthetic calcium carbonate (CaCO ). And the method for manufacturing this lamp reflector includes injection molding using high-pressure gas.

Lamp reflector and method of manufacturing the same

The invention provides a lamp reflecting mirror in which sufficient light reflecting characteristic (surface smoothness) can be obtained without application of any undercoat layer and in which heat resisting property, luminous intensity distributing performance (dimensional stability) and form retaining characteristic (material stiffness) at the time of adjustment of the optical axis can be satisfied at the same time. The lamp reflecting mirror is produced by injection molding a composition containing 30 to 50% by weight of polyphenylene sulfide resin, 5 to 30% by weight of calcium silicate whiskers, and 20 to 65% by weight of granular inorganic filler.

Lamp reflecting mirror comprising polyphenylene sulfide, calcium

The vehicular lamp assembly housing of the present invention is integrally formed of a synthetic resin, and in a plane shape thereof there is constituted an annular structure having a through hole for insertion therein of the rear end portion of a vehicular lamp assembly and at least a portion thereof is retracted in the depth direction to form a three-dimensional curved surface. The inner and outer peripheral portions of the annular structure are respectively formed with inner and outer peripheral edges bent backwards approximately perpendicularly from the plane portion of the annular structure. Further, between the said inner and outer peripheral edges there is formed an annular or generally annular, continuous reinforcing rib, and also formed a large number of connecting ribs at suitable intervals in a crossing relation to the reinforcing rib.
