ABSTRACT:
The hinge unit K of a variable capacity swash plate type compressor has support arms protruded to the back side of a rotor on the rotating drive shaft, and guide pins, one end of which is fixed to a rotatable and wobbling swash plate. The support arms have guide holes (guide surfaces) which extend in a predetermined direction having an angle .alpha. with respect to an axis perpendicular to the axis of rotation of the drive shaft. Sections perpendicular to the center lines L.sub.1 of the guide holes are formed into at least a partial circle. A spherical elements of the guide pins are slidably and rotatably engaged with the guide holes of the support arms to be in line contact with the guide surface of the guide holes. The angle .alpha. is set so that the top clearance TC of the respective pistons at both maximum and minimum compression capacities of the compressor is equivalent.
