ABSTRACT:
The present invention provides a rubber composition having a good balance among low temperature resistance, oil resistance, heat aging resistance, and mechanical strength characteristics. This rubber composition comprises a rubber component composed of an ethylenic copolymer rubber and an acrylic rubber, wherein the ethylenic copolymer rubber is a copolymer comprising (a) 50 to 85% by mole of ethylene, (b) 50 to 15% by mole of an acrylate and/or a methacrylate, and (c) 0.05 to 8% by mole, based on the total of said components (a) and (b), of a cross-linked point forming monomer; and the acrylic rubber contains at least 60% by mole of at least one monomer selected from among at least an alkyl acrylate, an alkyl methacrylate and an alkoxyalkyl acrylate.
