<p><P>PROBLEM TO BE SOLVED: To provide a piston seal member formed of a recyclable elastomer composition, and to provide a disc brake using the same. <P>SOLUTION: The piston seal member 8 holds a cylinder hole 6a and a piston for sliding in the cylinder hole 6a, in a liquid tight and slidable manner. The piston seal member 8 is formed of the elastomer composition which contains a thermoplastic elastomer having unsaturated bonds or groups having affinity with carbon nano-fibers and the carbon nano-fibers dispersed in the thermoplastic elastomer. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
