PURPOSE:To bring a low abrasion property of fluororesin into full play and thereby secure such a sliding seal surface that is low in sliding resistance and strong against separation by sticking a porous fluororesin film to the surface of a rubber seal part body. CONSTITUTION:A sliding seal surface of a windowpane 5 in an automobile is made up of sticking a porous fluororesin film 4 to the surface of a rubber seal part body 1. When suchlike surface treatment is performed, first a bonding agent 2 for rubber and an adhesive modified surface treatment agent 3 for fluororesin are mixed together with the rubber seal part body 1, and the porous fluororesin film 4 is solidly molded by extrusion. Next, vulcanizing is performed, thereby surface treatment is completed. With this constitution, a low abrasion property of the fluororesin is brought into full play, and thereby such a sliding seal surface that is low in sliding resistance and strong against separation is securable. |
