Abstract
The present invention aims to provide a cover for accommodating an air bag, having a high opening reliability, adaptable to a wide range of temperatures, having a good durability and a suitable touch, and providing a high productivity and a lower cost, and reducing the weight of the air bag apparatus as a whole. To attain the above object, the cover of the present invention is injection molded from a thermoplastic elastomer comprised of the following components (a), (b), (c) and (d), and having a hardness of between 60 and 85 measured according to JIS K 6301 TypeA. (a) a hydrogenated styrene and conjugated diene block copolymer of between 30 parts by weight and 55 parts by weight and obtained by hydrogenating a block copolymer composed of at least two polymer blocks including styrene units as a main part thereof and at least one polymer block including conjugated diene units as a main part thereof, a content of the styrene in the copolymer being between 20% by weight of the copolymer being 10.sup.5 or more; (b) a plasticizer to be used for a rubber, at between 25 parts by weight and 50 parts by weight; (c) an olefin group resin, at between 15 parts by weight and 30 parts by weight; (d) an additive of 5 parts by weight or less; wherein (a)+(b)+(c)=100 parts by weight.
