Zusammenfassung:	To reduce the weight of an entire rotary compressor.SOLUTION: A rotary compressor includes: a housing 2; a rotation shaft 3 extending in a vertical direction inside the housing 2; a cylinder 60 having, inside thereof, a compression chamber through which the rotation shaft 3 is inserted; and an upper bearing 4A and a lower bearing 4B rotatably supporting the rotation shaft 3 and fixed above and below the cylinder 60. The cylinder 60 is partially formed of a resin material.SELECTED DRAWING: Figure 1 【課題】ロータリ圧縮機全体の軽量化を図ることができる。【解決手段】ハウジング２と、ハウジング２内で鉛直方向に延びる回転軸３と、回転軸３挿通された圧縮室を内側に有するシリンダ６０と、回転軸３に回転可能に支持し、シリンダ６０の上下に固定される上部軸受４Ａ及び下部軸受４Ｂと、を備え、シリンダ６０は一部が樹脂材料で形成されるロータリ圧縮機を提供する。【選択図】図１
