PROBLEM TO BE SOLVED: To provide a rubber composition having a double bond in a molecule capable of providing a vulcanizate excellent in toughness without practically reducing processability of an unvulcanized material and vulcanizate property of the vulcanizate.SOLUTION: A rubber composition is manufactured by blending 100 pts.mass of a rubber having a double bond in a molecule capable of sulfur crosslinking, at least one kind of 1 to 100 pts.mass of carbon black and 10 to 150 pts.mass of an inorganic filler other than black carbon, 0.1 to 50 pts.mass of a sulfur-containing compounding agent, and 0.1 to 30 pts.mass of a hydrocarbon compound of which both terminal groups are thioesterified. |
