PROBLEM TO BE SOLVED: To provide a rubber composition containing an antioxidation agent and having excellent environmental conservation effect and improved aging resisting effect and abrasion resistance of the rubber. SOLUTION: The rubber composition contains 100 pts.wt. of a diene rubber, 0.5-3.5 pts.wt. of an aromatic secondary amine antioxidant, and tocopherol. The compounding ratio (weight ratio) of the aromatic secondary amine antioxidant to tocopherol is 0.25≤tocopherol/(tocopherol+aromatic secondary amine antioxidant)≤0.67. COPYRIGHT: (C)2007,JPO&INPIT
