PROBLEM TO BE SOLVED: To provide a rubber composition suitable for preparing a crosslinked molding excellent in ozone resistance and in heat resistance, and refusing to crack during a mandrel molding process, and to provide a molding prepared by crosslinking the composition. SOLUTION: The rubber composition contains a rubber compound comprising 40-90 wt.% of a nitrile copolymer rubber (A), 5-30 wt.% of a vinyl chloride resin (B), and 5-30 wt.% of a vinyl chloride-vinyl acetate resin (C). In the total weight of the rubber compound,≤3 wt.% is accounted for by one or more selected from the group consisting of zinc oxide, zinc salts of 10-20C aliphatic acids, and their mixtures.
