To prevent deterioration in oil in a compressor by using an alternative chlorofluorocarbon coolant.
A blade 8 for dividing the inside of a cylinder chamber 41 into a compression chamber X and a suction chamber Y is formed in one piece toward the outside in the diameter direction of a roller 7 fitted to an eccentricity section 22 of a drive shaft 21. The projection side tip section of the blade 8 is accepted by a receiving groove 11a in a support 11 for rotatably supporting a still member. The alternative chlorofluorocarbon coolant and an alternative coolant-adaptive oil are used for working fluid in the cylinder chamber 41 and lubricant in the compressor CP, respectively. The support 11 is made of one columnar member, and the receiving groove 11a penetrates the other side from one side of the outer periphery surface of the columnar member.
