PROBLEM TO BE SOLVED: To provide a rubber composition excellent in cut resistance and crack propagation resistance.SOLUTION: There is provided a rubber composition in which 2-30 pts.mass of at least one inorganic compound powder expressed by general formula (I): nM_xNaO_ySiO_zHO and having 10 μm or less diameter is formulated based on 100 pts.mass of a rubber component containing 1-100 mass% of a conjugated diene/non-conjugated olefin copolymer. In formula (I), M is an oxide or hydroxide of at least one metal selected from Al, Mg, Ti and Ca; n is an integer of 0-5; x is 0-1.0; y is an integer of 0-30; and z is an integer of 0-10, provided that at least one of n, x and y is not 0. |
