摘要： To provide a rubber composition capable of sufficiently abrading a sealing lip while sliding it in an initial stage of rotation and sufficiently reducing a running torque, and further capable of securing a sufficient sealing property. The composition includes a first compounding ingredient which is one or more kinds selected from the group consisting of calcium carbonate, magnesium oxide, aluminum oxide and barium sulfate in an amount of 50 to 200 parts by mass based on 100 parts by mass of a rubber component, and a second compounding ingredient which is one or two kinds selected from the group consisting of carbon black and a silica in an amount of more than 0 parts by mass and 50 parts by mass or lower.
