ABSTRACT:
A weather strip has a base portion to be mounted along an opening of a window of an automobile body and a seal portion projecting from the base portion to be come in contact with a window glass. The seal portion is composed of a pair of dogleg-shaped portions defining a hollow poriton of a nearly lozenge-shaped section, and a lip portion extending from a top of the hollow seal portion in a direction along an upper half portion of one of the pair of dogleg-shaped portions. The lip portion is pressed by the window glass when the window glass is closed. The thickness (T1) of the lip portion, the thickness (T2) of one of the pair of dogleg-shaped portions, and the thickness (T3) of another one of the pair of dogleg-shaped portions have a relation expressed by the following inequality:T1>T2>T3. And the lip portion extends in a direction approximate to a vertical direction as compared with the extending direction of the upper half portion of the one of the pair of dogleg-shaped portions. By providing a difference in thickness between the dogleg-shaped portions and the lip portion, an undesirable increase of the pressing load can be prevented, and accordingly, the seal force of the weather strip can be made uniform regardless of the change of the fitting condition of the window glass to the opening of the window.
