Abstract
A glass run channel comprising a glass run channel body composed of a bottom wall and side walls extending from two opposite edges of the bottom wall, the glass run channel body having a substantially U-shaped section and provided with a groove, and tonguelike draining parts protruding from vicinities of distal edges of the side walls toward the bottom wall of the glass run channel body so as to become proximate to each other. Each of the tonguelike draining parts has a window glass contact part composed of a surface to be brought into contact with a window glass, which comprises a layer of a thermoplastic elastomer and a layer of an ultrahigh molecular weight polyolefin composition. The layer of ultrahigh molecular weight polyolefin composition is arranged so as to contact a window glass. The ultrahigh molecular weight polyolefin composition comprises at least a polyolefin (composition) having a specified intrinsic viscosity and an olefinic thermoplastic elastomer. The glass run channel is excellent in the durability, tight contactability with a window glass exhibited when the window glass is held closed and supple slide exhibited when a window glass is closed or opened and, even when twisted or bent, is free from a creasing of the ultrahigh molecular weight polyolefin composition layer.
