PURPOSE:To make the compressive capacity of a compressor simply alterable with only replacement of each gear, by attaching gears, being engaged with each other, to a rotator of a motor and a crankshaft to be opposed to this rotator, while installing plural gears interposingly between these gears. CONSTITUTION:A motor 2 and a compressive element 2 are set up each in both upper and lower parts in a closed casing 1, and a rotator 21 of this motor 2 and the compressive element 3 are interlocked and connected with each other via a crankshaft 4. In this constitution, an internal gear 7, rotating together with the rotator 21, is attached to the top of the rotator 21 of the motor 2, while a gear 8, rotating together with the crankshaft 4, is attached to an upper end of this crankshaft 4 to be opposed to this internal gear 7. And, three intermediate gears 9 are installed between these gears 7 and 8 side by side at regular intervals, interlocking and connecting these gears 7 and 8. With this, at the time of altering compressive capacity of a compressor, each of these gears 7-9 are replaced with those different in the number of teeth, whereby turning power to be transmitted to the crankshaft 4 from the motor 2 is shifted in speeds 5.
