Provided are a polyphenylene ether resin composition having excellent fluidity and heat resistance, and a vehicle lighting fixture bezel formed of this resin composition and having light weight, excellent external appearance, and low water absorbency. The resin composition contains: (A) 42-57 mass % of a polyphenylene ether resin having a reduced viscosity of 0.39-0.43 dL/g (in chloroform solvent at 30&#xb0; C.); (B) 11-26 mass % of a polyphenylene ether resin having a reduced viscosity of 0.31-0.34 dL/g (in chloroform solvent at 30&#xb0; C.); (C) 9-15 mass % of a block copolymer including a vinyl aromatic hydrocarbon polymer block (c1) and a hydrogenated conjugated diene polymer block (c2); and (D) 15-23 mass % of a homopolymer of a vinyl aromatic hydrocarbon. The (C) block copolymer includes 62-70 mass % of vinyl aromatic hydrocarbon-derived monomer units, has a weight-average molecular weight Mw of 50,000-70,000, and has a molecular weight distribution Mw/Mn (Mn is number-average molecular weight) of 1.00-1.30.

A lamp device mounted on a vehicle includes a housing, a first translucent member defining a housing space together with the housing, a lamp unit housed in the housing space and including a light source, a sensor housed in the housing space and configured to detect information outside the vehicle based on invisible light, and a second translucent member housed in the housing space and covering the sensor. The second translucent member has transmittance of visible light lower than that of the first translucent member.

Lamp device

There is provided a vehicle lamp which uses a lamp body formed from a resin composition containing a base resin and a plant fiber, wherein a mold which is used to mold the lamp body is not corroded, and wherein if the lamp is manufactured by using the lamp body, fogging or an appearance failure is suppressed from being generated on an inner side of a front cover during usage. A vehicle lamp includes a lamp body which is opened at a front thereof, and a front cover which is attached to the lamp body to close a front opening portion of the lamp body, and the lamp body is formed from a resin composition which contains a base resin, a plant fiber and an acid scavenger.

Vehicle lamp having plant fiber

Provided is a vehicle lampusing a lamp bodyformed using a resin composition containing a base resin and plant fiber, in which the lamp bodyand a front coverhave good adhesiveness therebetween and there is no separation in the bonding between the lamp bodyand the front covereven after some time. The lamp bodyis formed using a resin composition containing a base resin and plant fiber, and in a bonding part between the lamp bodyand the front cover, the bonding is performed using a moisture curing adhesive.

Vehicle lamp

Disclosed is a process of preparing a moulded article, comprising 1) hydrolyzing a) at least one silane having one non-hydrolysable organic group, and b) at least one compound selected from b1) a silane having two non-hydrolysable organic groups, and b2) a hydrolysable polysiloxane, or a mixture thereof, and c) optionally at least one silane having no non-hydrolysable organic group, to prepare a composite composition comprising a hydrolysate or condensate, 2) placing the composite composition in a mould, 3) curing the composite composition to increase the degree of condensation, 4) removing the moulded article from the mould, and 5) heat treating the moulded article at a temperature of at least 100&#xb0; C. The moulded article is preferably an optical lens which may be used for automobile headlights.
