PROBLEM TO BE SOLVED: To reduce an amount of a leaked coolant at a compression stroke regarding a vane rotary compressor suitable for compression treatment of coolant gas for an air conditioner. SOLUTION: An inner wall shape at an intake port 11 side of a cylinder chamber 5 is an extended (flat) shape in an outward direction rather than an elliptical curve. In particular, 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 (larger than r1), and an elliptical curve range (angle zonesθ4 andθ9) defined by a second sine curve, as illustrated in Fig. 2.
