PROBLEM TO BE SOLVED: To provide a compression mechanism for arranging a motor in clean air atmosphere and also simultaneously effect cooling of a heat generating part. SOLUTION: By vertically moving a piston 4 via a crankshaft 9 through drive of a motor 1, air inputted in a crank case 2 is compressed via a filter 5. In a so constituted compression mechanism, the motor 1 is disposed in the crank case 2 so that the motor 1 is disposed in clean air atmosphere inputted through the filter 5, and a heat generating part is cooled by air which serves as a refrigerant. |
