A 2-stage rotary compressor is provided to improve friction performance by reducing contact areas while improving lubrication performance over the entire area between a wide low pressure eccentric part and a low pressure roller. An oil supply groove(122a) is formed between a rotation shaft(113) and rollers(123,133) engaged with the rotation shaft for supplying oil between the rotation shaft and the rollers, wherein the groove is formed in outer peripheral surfaces of eccentric parts(122,132) of the rotation shaft. |
