Abstract A side mold to be fixed onto a side of automobile body, comprising (A) a hard mold portion forming an outside main portion and (B) a soft mold portion forming an inner foot portion to be contacted with the side of automobile body; the hard mold portion being made of a blend of (a-1) a vinyl chloride polymer and (a-2) an ABS resin comprising a copolymer (i) of alpha -methylstyrene, styrene, acrylonitrile and methyl methacrylate and a graft-polymer (ii) in which at least one component of the copolymer is graft-polymerized onto a butadiene rubber; and the soft mold portion being made of a plasticized polyvinyl chloride and having a JIS-A hardness of 50 DEG to 90 DEG . The side mold is light even if the side mold is made large, and has sufficient strength, surface hardness and shock observer effect.
