PROBLEM TO BE SOLVED: To prevent an abnormal temperature rise in the inside of cylinders 1, since wear of a piston cup 4 directly affecting a service life of an air compressor 12 is affected by the inside temperature of the cylinders 1 contacting with the piston cup 4. SOLUTION: Cooling fins 6 are mounted to the cylinders 1 of the air compressor 12 so as to be capable of being easily separated and removed from the cylinders 1. This structure facilitates heat release of the cylinders 1, and prevents abnormal heating of the cylinders 1. In addition, at the time of replacement in maintenance and inspection of the air compressor 12, the cylinders 1 and the piston cup 4 can be easily replaced by removing four cylinder head setscrews 29 fixing a cylinder head 3, and the air compressor 12 can be regenerated by replacing only these components.
