Abstract

Abstract This invention is directed to a weather strip for use in an automobile, the main body of which is provided in the portion thereof destined to contact sheet metal parts such as a body flange or a sash with a strip of rustproofing member. The rustproofing member comprises a core, a core coating layer, and a surface layer, the core formed of a fabric impregnated with a rustproofing agent or a rustproofing material such as of a highly absorbent polymer, the core coating layer formed of a water-diffusing material, and the surface layer formed of a flexible planar material. The planar material is furnished at least on the side thereof contiguous to the metal sheet part with a water-permeating texture.
