Abstract
A weather strip for sealing the joint between the door frame of the body of a car and a door put on the door frame comprises, in an integral structure, a welt part of a substantially U-shaped cross section to be put on a flange formed on the door frame, a hollow sealing part protruding from the outer side wall of the welt part, and a fish-bone or one-side core having a plurality of U-shaped loops and a linear connecting part successively connecting the U-shaped loops, and buffed in the welt part. Slots or cuts are formed in sections of the weather strip to be extended on the lower side of the door frame to cut out portions of the connecting part of the core so that breaks are formed in the connecting part of the core to make the section of the weather strip stretchable and contractible.
