By providing the lower convex arc-shaped portion having a substantially elliptical hollow cross section, the load characteristic of the weather strip is made flat with respect to the amount of bending, and the change in the building (step) is reduced. In addition, the circular elastic member does not require bonding of the upper and lower contacts of the elastic member due to the intervention into the elliptical hollow cross section by the upper convex circular arc portion and the lower convex circular arc portion, and the lower convex circular arc portion is the holder. Achieve the purpose simply by oppressing and contacting.

前記下側凸円弧状部7bが弾圧当接する。According to the present invention, the first lip 7 has the following shape and structure. That is, the weather strip body 2a
And an upper convex arcuate portion 7a integrally formed with the upper convex arcuate portion 7a and a lower convex arcuate portion 7b integrally formed with the upper convex arcuate portion 7a, and the upper convex arcuate portion 7a is a weather. The strip main body 2a is made of the same material as EPDM (ethylene-polyprene rubber) solid, and the lower convex arc-shaped portion 7b is formed of EPDM (ethylene-polyprene rubber) foam, foam such as sponge. In addition, 10 is a holder formed on the weather strip body 2a below the first lip 7,
The lower convex arcuate portion 7b comes into elastic contact.
