The utility model provides a compressor. The cross-sectional area of the outer peripheral side of the blade groove is smaller than the cross-sectional area of the inner peripheral side of the blade groove. The area of the force received by the blades in the roller direction is reduced. therefore, the contact force between the roller and the blades is reduced; a gas containing part capable of selectively forming suction pressure and intermediate pressure is formed between the blades and the blade grooves. the contact force between the blades and the roller is properly controlled; contact surfaces of the blades facing the roller are widely formed on one side of the compression chamber. A space portion forming the discharge pressure is formed on a side surface of the blade and at least eitherside of the cylinder corresponding thereto to reduce a lateral reaction force applied to the blade, thereby reducing a loss of mechanical friction between the blade and the cylinder, to appropriatelyreduce a contact force between the roller and the blade.
