An automobile weatherstripping includes an extrusion-formed part and a mold-formed part, the mold-formed part being welded and integrated with the extrusion-formed part. The extrusion-formed part is made of an olefin elastomer and the mold-formed part is made of a resin composition containing an olefin resin, ethylene-alpha-olefin copolymer rubber, hydrogenated aromatic vinyl conjugated diene compounds block copolymer mineral oil and at least one of natural rubber and butadiene rubber in predetermined proportions. The extrusion-formed part and the mold-formed part have a sufficient level of bonding strength with no bonding agent layer being used therebetween. |
