Zusammenfassung:	To reduce vibration of a rotary compressor.SOLUTION: In a rotary compressor, outer peripheral surfaces of two cylinders (30 and 35) are provided with first openings (30a and 35a) constituting suction ports (33 and 38) communicating with suction side spaces (S1 and S1) respectively, one first opening (30a) and the other first opening (35a) of the two cylinders (30 and 35) are arranged so as to be shifted from each other in the circumferential direction of the two cylinders (30 and 35) when viewed from the axial direction of a drive shaft (70), and a first mechanism (80) for reducing a difference between suction closing angles in the two cylinders (30 and 35) is provided.SELECTED DRAWING: Figure 4 【課題】ロータリ圧縮機の振動を低減する。【解決手段】ロータリ圧縮機は、２つのシリンダ（30,35）の外周面のそれぞれには、吸入側空間（S1，S1）に連通する吸入ポート（33,38）を構成する第１開口（30a，35a）が設けられ、２つのシリンダ（30,35）の一方の第１開口（30a）および他方の第１開口（35a）は、駆動軸（70）の軸方向からみて、シリンダ（30,35）の周方向に互いにずれて配置され、２つのシリンダ（30,35）における吸入閉じ切り角度の差を小さくする第１機構（80）が設けられている。【選択図】図４
