Abstract: Resin moldings are taught that have relatively low coefficients of linear expansion. For example, resin moldings may primarily comprise a polypropylene resin and/or an olefin-based thermoplastic elastomer. Composite products (10) may include at least two integrated resin-molded parts (12, 14, 16, and 18) whose compositions are different from each other, and at least one resin-molded part (18) may be comprised primarily of a polypropylene resin or olefin-based thermoplastic elastomer. The resin molding or at least one resin-molded part preferably contains a fibrous filler, which preferably comprises primarily carbon fibers, at a weight percentage of between about 1 and 10% and a powder filler (e.g., talc) at a weight percentage of between about 0 and 50%. The fibrous filler and the powder filler preferably serve as expansion/contraction suppression components for the resin material.

Abstract: A long weather strip includes an attach portion attachable along a window frame for vehicle, and a lip portion for sealing a glass window pane for vehicle. The lip portion protrudes from the attach portion toward the glass window pane to be in contact therewith. The glass window pane is movable within the window frame. The lip portion includes a rough surface portion pressed onto a face of the glass window pane and made of a molding material containing the following (a) to (c) : (a) olefin thermoplastic elastomer in which a content ratio of polyolefin resin as a hard segment is 50 mass % or more as a whole, (b) solid particles having an average particle diameter in a range from 1 to 100 ?m, and (c) liquid lubricant. The rough surface portion has a surface formed in a corrugation state with a number of small projections with the solid particles.
