Zusammenfassung:	A rotary compressor according to an embodiment includes a case, a rotary shaft, a compression mechanism, a balancer, and a balancer cover. A through-hole is formed in the balancer cover at a position of the balancer cover facing the rotary shaft in an axial direction. The rotary shaft has a thrust sliding portion, a protruding portion, and a supply channel. The thrust sliding portion comes into contact with a seal located around the through-hole of the balancer cover, in the axial direction of the rotary shaft. The protruding portion is located on an inner peripheral side with respect to the thrust sliding portion and protrudes downward from a lower end of the through-hole through the through-hole. The supply channel is open on a lower end surface of the protruding portion to guide a lubricating oil.
