This rotary compressor has a case, a rotating shaft, a compression mechanism, a balancer, and a balancer cover. A through-hole is formed at a position in the balancer cover that is facing the rotating shaft in the axial direction. The rotating shaft has a thrust sliding section, a protruding section, and a supply path. The thrust sliding section abuts a seal section positioned around the through-hole in the balancer cover, in the axial direction of the rotating shaft. The protruding section is positioned on the inner circumference side of the thrust sliding section and protrudes through the through-hole, to protrude further below the lower end of the through-hole. The supply path opens at the lower end face of the protruding section and guides lubricating oil.
