A cellulose fiber-reinforced polyolefin resin composition contains a polyolefin resin, a cellulose fiber having a fiber length of 1 &#x3bc;m or more, an acid-modified elastomer, and high-density polyethylene. In the composition, an amount of the cellulose fiber is 6 to 95 parts by mass relative to 100 parts by mass of the polyolefin resin, an amount of the acid-modified elastomer is 0.5 to 1.2 times by mass the amount of the cellulose fiber; and, an amount of the high-density polyethylene is 15 to 55 parts by mass relative to 100 parts by mass of the polyolefin resin.

An onboard sensor cover includes a cover body that includes front and rear bases and a decorative layer. The front base is made of a transparent plastic material that permits passage of an infrared ray and a millimeter wave and includes a rear surface in the transmission directions of the infrared ray and the millimeter wave that is configured by a first uneven surface. The rear base is made of a plastic material that permits passage of the infrared ray and the millimeter wave and includes a front surface in the transmission directions that is configured by a second uneven surface. The decorative layer is made of a material that reflects visible light and permits passage of the infrared ray and the millimeter wave and is in contact with the first and second uneven surfaces. The front and rear bases are made of the same type of plastic material.

A foamable polypropylene resin composition includes 10 parts by mass to 65 parts by mass of rubber or a thermoplastic elastomer, 18 parts by mass to 90 parts by mass of talc having a 50% particle diameter (D50) of 1 &#x3bc;m to 3 &#x3bc;m and surface-treated for increased dispersibility, 0.1 part by mass to 6.0 parts by mass of an organic crystal nucleating agent, and 5 parts by mass to 15 parts by mass of a foaming agent relative to 100 parts by mass of the polypropylene resin.

Foamable polypropylene resin composition and molded body

The present invention provides a resin material composition including 25 to 65% by mass of a thermoplastic polyolefin resin, 0.5 to 22% by mass of a glass wool, and 5 to 35% by mass of a thermoplastic elastomer.

A filler neck is equipped with a neck main body having a pipe shaped resin inner layer and resin outer layer, and a retainer made of metal mounted so as to cover the edge part of the neck main body. The resin inner layer and the resin outer layer are made of resin materials for which one layer has superior fuel permeability resistance to the other layer. The resin inner layer has a screw part for screwing into a screw part of a fuel cap on the inner wall of the resin inner layer. The retainer has a seal part for sealing between the gasket, and a round cylinder shaped outer circumference protector part. The lower end of the outer circumference protector part is on plane perpendicular to the center axis of the fuel path. The plane includes the screw part.
