Abstract
The present invention relates to a trim or a seal member such as an opening trim weather strip. The trim or a trim body in the seal member has a holding lip portion and modified holding lip portions. And the holding lip portion and modified holding lip portions have head portions. The head portions are made to bulge out toward a bottom wall portion at the tip ends of modified holding lip portions of the trim or the trim body of trim portion. The modified holding lip portions are formed so that projecting lengths of the head portions from the end surfaces of tip end portions of the modified holding lip portions, and the thicknesses of the head portions increase in inverse proportion to lip projecting lengths of the modified holding lip portions from an inner surface of an interior side wall portion. Alternatively, a slope inclined with respect to an extension plane of an opening-portion-side surface of a base end portion is formed at tip ends of the modified holding lip portions. The slope is formed so that the inclination angle with respect to the extension plane increases in accordance with the projecting lengths of the modified holding lip portions.
