Disclosed is a weather strip comprising: (a) a solid rubber made retainer; (b) a plurality of retainer lips projecting from the inside of the retainer, the retainer lips being arranged to oppose each other and adapted such that the flange of an automobile body is inserted into the space formed by the opposing retainer lips; and (c) a projection which is provided on the end of at least one pair of the retainer lips among the plurality of retainer lips and projects toward the innermost surface of the retainer so as to be pressure-contacted by the flange of the automobile body. The pair of retainer lips having the projection come into contact with each other at the portion where the projections are provided and open gradually toward the open end of the retainer. Two pairs of retainer lips are provided inside the retainer, toward the open end and the innermost surface opposing the open end, respectively, and the pair of retainer lips having the projection is that which is located close to the innermost surface of the retainer.

A weather strip comprising: a channel-shaped solid-rubber retainer having side walls, a bottom wall and an open mouth, two pairs of opposed flange-like retainer lips composed at least in part of solid rubber, said retainer lips projecting inward from said side walls with the lips of each of said pairs inclined toward said bottom wall and adapted to receive therebetween, press on, engage and retain said strip on, a flange of an automobile body when said strip is pressed thereon open mouth first, one side of said flange facing the outside of said body; a pair of opposed flange-like sub-lips composed at least in part of solid rubber, said sub-lips protruding inward from the tips of the lips of at least that pair of said lips located closer to said retainer bottom wall than the other pair, said sub-lips being inclined toward said bottom wall at a greater angle than that of said lips and facing said open mouth being divergent theretoward, said sub-lips having convexly rounded tips and being substantially devoid of concave surfaces and the sides thereof being disposed generally at an angle other than zero with respect to the corresponding sides of their respective lips, at least the side portion of one of the lips of the other pair closest the retainer open mouth, and which lip side portion faces said open mouth and inward of said body, being made of sponge rubber, whereby the area of contact of said retainer with said flange is increased with resultant increase of the retaining force of said retainer while the force required to press said retainer on said flange is reduced.
