ABSTRACT:
A variable displacement swash plate type compressor has a coupling structure between a drive shaft and a swash plate in order to allow the swash plate to be movable along the drive shaft and inclinable relative to the same. The coupling structure comprises a bearing portion provided on the drive shaft to rotate therewith. The bearing portion includes first and second semicylindrical outer walls which are symmetrically arranged with respect to an axis of the drive shaft and first and second flat side walls which are symmetrically arranged with respect to the axis. Each of the first and second semicylindrical outer walls is perpendicular to each of the first and second flat side walls. The bearing portion further includes a rectangular center bore formed in a hub portion of the swash plate. The center bore is so sized and shaped as to intimately and slidably receive therein the bearing portion.
