PROBLEM TO BE SOLVED: To feed fluid flowing out to dead space through an inflow port into a cylinder chamber without turning the fluid in the dead space. SOLUTION: The rotary compressor is provided with an outside cylinder part (42) and inside cylinder part (43) forming an annular cylinder chamber (60, 65), a cylinder (40) accommodated in the upper housing (35) to form dead space (57) in a gap with upper housing (35), and an annular piston (52) accommodated in the cylinder chamber (60, 65). The cylinder (40) is eccentrically rotated with respect to the annular piston (52). A suction port (39) passing through in a radial direction is formed in the upper housing (35). A through hole (44) passing through in a radial direction is formed in the outside cylinder part (42). An axial center of the suction port (39) is shifted in an opposite direction to an eccentrically rotating direction of the cylinder (40) with respect to an axial center of the through hole (44) in a circumferential direction of the housing (35).
