PURPOSE:To prevent the occurrence of chattering, by a method wherein the peripheral surface of the cam of a vane compressor is formed with a round part, an increase curve part, increasing a vane protrusion amount, a steady curve part, a decrease curve part, and a round part. CONSTITUTION:A pump housing 4 is formed with a cam ring 5, a front side block 6, and a rear side block 7. A cam peripheral surface 5a is formed with a round part A to seal a gap between the outer peripheral surface of a rotor 8 and the inner peripheral surface of the cam ring 5, an increase curve part B to increase a protrusion amount of a vane, a steady curve part C, a decrease curve part D, and a round part E. This constitution prevents the occurrence of chattering, reduces the occurrence of a fluctuation in torque, and besides provides a high delivery amount.
