PROBLEM TO BE SOLVED: To prevent foreign matters in the air from adhering to a driving part. SOLUTION: In an air compressor 10, a pair of tanks 14 and 16 formed into cylindrical shapes are supported in parallel on a frame 12, and an air compressing part 18 to generate compressed air and the driving part 20 to drive the air compressing part 18 are mounted on upper parts of the tanks 14 and 16. Further, an integrally formed resin cover 22 is mounted on the upper parts of the tanks 14 and 16 to cover the air compressing part 18 and the driving part 20. The cover 22 has a second air introduction port 22n to introduce air flow to cool the driving part 20 on a lower surface side. Even if wood shavings and wood flour float in the air around the air compressor 10, a possibility that the wood shavings and wood flour are sucked into the air introduction port 22n opened on a lower surface side is reduced, entering of dust into the driving part 20 is prevented, and a motor 68 of the driving part 20 is prevented from having a defective operation by the foreign matters.
