Disclosed is a rubber composition for direct vulcanization bonding, comprising (A) an ethylene-α-olefin-based copolymer rubber comprising an ethylene unit and an α-olefin unit having 3 or more carbon atoms, (B) a silane coupling agent comprising a sulfur atom, and (C) a vulcanizing agent comprising sulfur. The content of the silane coupling agent is 2.7 to 12 parts by mass per 100 parts by mass of the ethylene-α-olefin-based copolymer rubber. This rubber composition is used for forming a molded rubber directly vulcanization bonded to a metal member. |
