    摘要: In a scroll type compressor, a simple structure provides oil intake assistance to ensure that lubricating oil in an oil space is induced into a spiral groove in correspondence to the rotation rate of a drive shaft. The drive shaft is provided with an inclined spiral groove which is formed in the external circumferential surface of the drive shaft. The drive shaft slides in contact with a main bearing. A leading end of the spiral groove, in the direction of the rotation of the drive shaft, communicates with the oil space and a trailing end of the spiral groove opens into the lubricating oil reservoir. The lubricating oil is supplied to the area where the drive shaft slides in contact with the main bearing by the spiral groove. Also, upon rotation of the drive shaft, intake of lubricating oil into the spiral groove is assisted when the suction force is reduced due to a high rotation rate.
