Abstract
A gas compressor has a cup-like casing. A driving shaft is rotatably carried by a bottom of the casing and has a rotary plate secured thereto. A driven shaft is disposed in the casing at an inclination angle of 20.degree. against the driving shaft, supported by a bearing provided on an end of the driving shaft, and driven by the driving shaft. A cylinder block is fixed to the driven shaft and has a cylinder bores receiving pistons coupled with the rotary plate so that the pistons reciprocate in the cylinder bores upon rotation of the driving shaft. A side plate is secured to an open end of said casing and has a bore receiving a bearing for supporting one end of the driven shaft. The bore is formed in the inside the side plate which projects outside, so that a distance between the bearing of the driving shaft and the bearing in the bore is extended and stable.
