Abstract
Official abstract text for this publication.
A pair of gaskets is integrally formed with seal lips corresponding to each other and extending in the longitudinal direction of the gasket, and side portions disposed on either sides or one side of the seal lip and having a height lower than that of the seal lip. The plate-shaped attachment member includes a through-hole provided at a position where the side portions of the pair of gaskets communicate with each other so as to be formed therethrough in the thickness direction, and the pair of gaskets is integrally formed through the through-hole. An opening shape of the through-hole is set to be an elongated shape in the longitudinal direction of the gasket so as to make a width dimension of each of the side portions as small as possible.
