According to one embodiment, a rotary compressor includes a compression mechanism unit. When H is the length of a middle shaft part, Hp is the length of a bearing hole, Dp is the inner diameter of the bearing hole, Dc is the outer diameter of a crank part, Dm is the outer diameter of the middle journal part, Cis the axial length of a first chamfered part provided to a middle shaft part-side end edge of the crank part, Cis the axial length of a second chamfered part, Cis the axial length of a third chamfered part, and Cis the axial length of a fourth chamfered part, Dp is larger than Dc and Dm, and the relationships of [Equation 1] H≤Hp, [Equation 2] H>Hp−C−C−√{square root over ((Dp−Dc))}, and [Equation 3] H>Hp−C−C−√{square root over ((Dp−Dm))} are all satisfied.
