Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a highly elastic rubber composition which uses a vulcanization accelerator having a vulcanization-retarding effect equal to or larger than that of DCBS without using such a vulcanization retarder as CTP having possibility causing problems such as the deterioration of rubber physical properties and blooming after vulcanized, prevents the deterioration of the rubber physical properties, has good workability and is excellent in crack resistance. SOLUTION: There is provided the rubber composition characterized by comprising a rubber component, a sulfenamide-based vulcanization accelerator represented by formula (I) [wherein, R1is a 3-12C branched alkyl; R2is a 1-10C straight chain alkyl or a 3-10C branched alkyl; R3to R6are each identically or differently H, a 1-4C straight chain alkyl or alkoxy, or a 3-4C branched alkyl or alkoxy; (n) is 0 or 1; (x) is 1 or 2], trans-polybutadiene, and sulfur.
