Zusammenfassung:	To provide a rubber composition that has enhanced anti-oxidation and anti-aging performance to a level higher than a conventional level.SOLUTION: A rubber composition is produced by blending Mb pts.mass of at least one tocopherol compound selected from tocopherol and a derivative thereof and Ma pts.mass of a primary amine compound having a primary amino group into 100 pts.mass of a rubber component and has a ratio (Ma/Mb) of the blending amount (Ma) of the primary amine compound to the blending amount (Mb) of the tocopherol compound of 0.5 to 5.0.SELECTED DRAWING: None 【課題】耐酸化老化防止性能を従来レベル以上に向上させたゴム組成物を提供する。【解決手段】ゴム成分１００質量部に、トコフェロールおよびその誘導体から選ばれる少なくとも１つのトコフェロール化合物をＭｂ質量部と、１級アミノ基を有する１級アミン化合物をＭａ質量部配合してなり、前記１級アミン化合物の配合量（Ｍａ）と前記トコフェロール化合物の配合量（Ｍｂ）の比（Ｍａ／Ｍｂ）が０．５〜５．０であることを特徴とする。【選択図】なし
