Compressor

A compressor comprising:

• a compression element including a cylinder having a compression space formed therein;
• a suction port and a discharge port which communicate with the compression space in the cylinder;
• a compression member having continuous thick and thin parts, one surface of the compression member being inclined, the compression member being arranged in the cylinder to rotate, the compression member compressing fluids sucked through the suction port and discharging the compressed fluids through the discharge port;
• a substantially rectangular vane which is arranged between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space of the cylinder into a low pressure chamber and a high pressure chamber,
• wherein another surface of the compression member is inclined to approach a peripheral part thereof to one surface side.
