<p>A variable displacement swash plate type compressor (100A) has a coupling structure between a drive shaft (11) and a swash plate (15) in order to allow the swash plate (15) to be movable along the drive shaft (11) and inclinable relative to the same. The coupling structure comprises a bearing portion (40) provided on the drive shaft (11) to rotate therewith. The bearing portion (40) includes first (40A) and second (40B) semicylindrical outer walls which are symmetrically arranged with respect to an axis of the drive shaft (11) 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 (40A,40B) are perpendicular to each of the first and second flat side walls. The bearing portion (40) further includes a rectangular center bore (20) formed in a hub portion of the swash plate (15). The center bore (20) is so sized and shaped as to intimately and slidably receive therein the bearing portion (40). <IMAGE></p> |
