PROBLEM TO BE SOLVED: To improve volume efficiency of a vane rotary compressor. SOLUTION: An inner wall shape at an intake port 10 side of a cylinder chamber 5 is extended to an outward (intake port 10 side) direction rather than an elliptical curve. The inner wall shape of the cylinder chamber 5 is formed by an arc range (angle zonesθ1,θ5,θ6, andθ10) defined by an arc of a radius r1, an elliptical curve range (angle zonesθ2 andθ7) defined by a first sine curve, an arc range (angle zonesθ3 andθ8) defined by an arc of a radius r2 (greater than r1), and an elliptical curve range (angle zonesθ4 andθ9) defined by a second sine curve as illustrated in Fig. 2. The curvature radius of the arc range (angle zonesθ3 andθ8) is the same as the curvature radius of the elliptical curve range (angle zonesθ4 andθ9), or is larger than the curvature radius of the elliptical curve range (angle zonesθ4 andθ9).
