摘要： A variable displacement compressor having a swash plate capable of being changed with inclination angle for converting the rotation of a drive shaft into the reciprocating motion of pistons comprises a plurality of urging means each having one end brought into contact with the swash plate and urging the swash plate in the direction of increasing an inclination angle of the swash plate, wherein the plurality of urging means are constructed so that the number of urgings is increased as the inclination angle of the swash plate is decreased. The freedom of adjustment of the urging force due to the urging means for increasing the inclination angle of the swash plate can be enlarged by a simple structure, and the urging force can be finely adjusted in accordance with the inclination angle of the swash plate. Consequently, the adjustment of the urging force due to the urging means for urging the swash plate in the inclination angle increasing direction can be optimized, and the swash plate can be allowed to perform a desirable operation near the minimum inclination angle.
