Zusammenfassung:To facilitate a process of manufacturing a bearing, etc.SOLUTION: A rotary compressor 1 includes: a closed housing 2 constituting an outer shell; an electric motor 5; a compression mechanism 6 accommodated in the closed housing 2 and compressing a refrigerant by using driving force from the electric motor 5; and a driving shaft 14 coupling the electric motor 5 and the compression mechanism 6 and rotating about a central axial line extending in the vertical direction. The compression mechanism 6 includes: an upper rotor 33 coupled to the driving shaft 14 and accommodated in an upper cylinder chamber 31; an upper cylinder body part 34 partitioning a radial outer side of the upper cylinder chamber 31; and an upper bearing part 35 rotatably supporting the driving shaft 14 and partitioning the vertical direction of the upper cylinder chamber 31. The refrigerant is compressed between the rotating upper rotor 33 and the upper cylinder body part 34, and the upper bearing part 35 and the upper cylinder body part 34 are formed of a composite material formed by reinforcing resin by using reinforced fiber.SELECTED DRAWING: Figure 1 【課題】軸受等を製造する工程を容易化することを目的とする。【解決手段】ロータリ圧縮機1は、外殻を為す密閉ハウジング2と、電動モータ5と、密閉ハウジング2に収容され、電動モータ5からの駆動力によって冷媒を圧縮する圧縮機構6と、電動モータ5と圧縮機構6とを連結し、上下方向に沿って延在する中心軸線を中心として回転する駆動軸14と、を備えている。圧縮機構6は、駆動軸14と連結され上部シリンダ室31に収容される上部ロータ33と、上部シリンダ室31の半径方向の外側を区画する上部シリンダ本体部34と、駆動軸14を回転可能に支持し上部シリンダ室31の上下方向を区画する上部軸受部35と、を有し、回転する上部ロータ33と上部シリンダ本体部34との間で冷媒を圧縮し、上部軸受部35及び上部シリンダ本体部34は、強化繊維で樹脂を強化した複合材で形成されている。【選択図】図1
