To reduce an amount of oil flowing to the outside of a compressor.SOLUTION: A compressor (10) includes: a balance weight (66) provided at a lower end of a rotor (65) and including a lower end located below a lower end of a coil (63); an outer gas passage (61a) which is formed at the outer side of a stator (61) so as to extend in a vertical direction; and a wall part (100) which protrudes downward from the stator (61) and encloses the balance weight (66). A lower end of the wall part (100) is located below the lower end of the balance weight (66).SELECTED DRAWING: Figure 5 【課題】圧縮機の外部へ流出する油の量を低減する。【解決手段】圧縮機（10）は、回転子（65）の下端に設けられ、その下端がコイル（63）の下端よりも下に位置するバランスウエイト（66）と、固定子（61）の外側に上下方向に延びるように形成された外側ガス通路（61a）と、固定子（61）から下方に突出し、上記バランスウエイト（66）の周囲を囲む壁部（100）とを備える。そして、壁部（100）の下端は、上記バランスウエイト（66）の下端よりも下に位置する。【選択図】図５
