<P>PROBLEM TO BE SOLVED: To previously prevent collapse deformation of a hollow seal lip at a corresponding part to a corner part without increasing reaction force of the lip. <P>SOLUTION: A projection 11 is integrally formed in the hollow seal lip 3 integrally formed with a welt part 2 having an approximately U shape cross section directed from a terminal part 9a side of a peripheral wall part 9 of the seal lip 3 itself to a side wall part 10 side of the welt part 2. In the case where one terminal part 9a of the peripheral wall part 9 receives tensile force at the corresponding part of the corner part of a flange part F and the seal lip 3 is subjected to collapse deformation, the projection 11 is butted to the side wall part 10 to be resistant thereto and much more collapse deformation is prevented. <P>COPYRIGHT: (C)2004,JPO |
