Abstract A variable capacity type compressor has a swash plate which can incline with respect to the drive shaft. An angle decreasing spring urges the swash plate to decrease the inclination angle and a return spring urges the swash plate to increase the inclination angle from the minimum inclination angle beyond the limit angle. The minimum inclination angle is smaller than a limit angle at which the swash plate can be assuredly returned in the direction to increase the inclination angle by a reaction force of the discharge pressure, and the angle decreasing spring balances with the return spring at an angle greater than the limit angle. A minimum spring load (F0) of the return spring is greater than 20N. A maximum spring load (F100) of the angle decreasing spring is F100(N) = (180 +/- 30) – 4 x (VD – 120).
