<P>PROBLEM TO BE SOLVED: To provide: a rotary compressor inhibiting sliding loss of an eccentric part of a rotary shaft and an eccentric roller, eliminating insufficient stiffness of a rotary shaft connection part, preventing flexible deformation, and improving compression performances; and a refrigeration cycle device provided with the rotary compressor and improving refrigeration cycle device. Ž<P>SOLUTION: In this rotary compressor, expression (1) Rc<Rm+e and expression (2) Rc≥Rs+e are satisfied where eccentric part radius of the rotary shaft is represented by Rc, main shaft part radius by Rm, auxiliary shaft part radius by Rs, and, eccentric quantity of the eccentric part by e, expression (3) (2L-H)/(D+2e)≥0.5 is satisfied where axial length of a connection part is represented by L, shaft diameter of the connection part by (ϕ)D and axial length (thickness) of the eccentric roller by H, and expression (4) (ΔP×Dro×H×L<SP>3</SP>)/(E×M)≤0.02 (mm) is satisfied where differential pressure of delivery pressure and suction pressure is represented by ΔP, outer diameter of the eccentric roller by (ϕ)Dro, Young's modulus of the rotary shaft by E, second moment of area of the connection part by M, and cylinder inner diameter of the connection part by (ϕ)Di. Here, M=πX(D<SP>4</SP>-Di<SP>4</SP>)/64. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
