A variable displacement compressor has a housing, a drive shaft, a rotor, a swash
plate, a piston and a decelerating mechanism. The housing includes a cylinder bore
and supports the drive shaft. The rotor is secured to the drive shaft. The swash
plate is operatively connected to the rotor and the drive shaft so as to rotate
therewith and varies its inclination angle relative to the drive shaft. The piston
is connected to the swash plate so as to reciprocate in the cylinder bore with
rotation of the swash plate. A stroke of the piston varies in accordance with the
inclination angle of the swash plate. The deceleration mechanism between the rotor
and the swash plate decelerates the inclination speed of the swash plate in a range
from a near maximum inclination angle to the maximum inclination angle when the
swash plate inclines to increase the stroke of the piston.
