An acrylic rubber composition comprising 5 to 15 parts by weight of a plasticizer having a solubility parameter SP value (by Small's method) of 8.5 to 10.5 based on 100 parts by weight of super cold resistant grade acrylic rubber having a glass transition point Tg of −42° C. or less, wherein the acrylic rubber composition can give a vulcanizate with the TR10 value, which is an index of cold resistance, of −42° C. or less both initially and after oil dipping. In the acrylic rubber composition, first, the ratio of an acrylate monomer that constitutes acrylic rubber is adjusted, thereby the low temperature characteristics can be maintained even in an oil contact environment. This intentionally reduces the oil resistance of the vulcanized rubber molded product, thereby increasing the amount of oil swelling into the vulcanized rubber molded product and improving the flexibility in a low temperature environment.
