A rubber composition permits good adhesion upon crosslinking to fiber materials and offers good adhesion after thermal aging. The rubber composition includes about 1/10 to about 1/1000 mol of an organic peroxide and either about 0.5 or about 10 parts by weight of an organic compound having two or more acrylate groups or methacrylate groups and one or more carboxyl groups in the molecular structure or about 1 to about 30 parts by weight of a carboxy-modified rubber per 100 parts by weight of a rubber crosslinkable with the organic peroxide.
