Provided is an acrylic rubber composition which gives a vulcanizate having excellent heat resistance, in particular, having an excellent balance between the retention of tensile strength and the retention of elongation after heat aging. Also provided are a hose part, a sealing part, and a vibration-damping rubber part each obtained from the composition. The acrylic rubber composition contains an acrylic rubber obtained by copolymerizing 100 parts by mass of an alkyl acrylate with 10 to 100 parts by mass of an alkyl methacrylate and 0.5 to 4 parts by mass of a crosslinkable monomer. The alkyl methacrylate preferably is at least one compound selected from the group consisting of methyl methacrylate, ethyl methacrylate, and n-butyl methacrylate. The alkyl acrylate preferably is at least one compound selected from the group consisting of methyl acrylate, ethyl acrylate, and n-butyl acrylate.
