Abstract
Abstract A steering wheel is described, which comprises a core that is covered with a synthetic resin covering material which is overlaid with a coating film thereon, wherein said covering material is formed using an injection molding method by a resin composition that comprises 100 parts by weight of a polyvinyl chloride resin, 100 to 200 parts by weight of a phthalic acid ester based plasticizer represented by formula (I) and 10 to 40 parts by weight of an acrylonitrile-butadiene rubber: ##STR1## wherein R 1 and R 2 are each an alkyl group, provided that when the total number of mols of R 1 and R 2 is 100 mol, a monomethyloctyl group is present in an amount of 10 to 60 mols, while a dimethylheptyl group is present in an amount of 30 to 70 mols.
