To obtain a rotary compressor in which a rotary shaft is difficult to deflect, and a sub-shaft part and a main shaft part of the rotary shaft are difficult to bite into a sub-bearing part of a lower end plate and a main bearing part of an upper end plate.

In a rotary compressor 1, a vane pump 155B arranged in an oil supplying vertical hole 155 of a rotary shaft 15 supplies lubrication oil stored in a lower part of a compressor housing 10 to first and second compressing parts 12S and 12T, a main shaft part 153, and a sub-shaft part 151, via the oil supplying vertical hole 155, first and second eccentric-part oil supplying horizontal holes 156S and 156T, an intermediate oil supplying horizontal hole 159, a surface of an outer circumference of an intermediate shaft part, first and second eccentric part oil grooves 157S and 157T, a sub-shaft part oil groove 158S, and a main shaft part oil groove 158T.
