Abstract
Provided is an assembly structure of a drive shaft and a swash plate in a swash plate type compressor including a housing, a cylinder block having a plurality of cylinder bores, a drive shaft rotatably supported by the cylinder block or the housing, a swash plate installed at the drive shaft to vary its tilt angle with respect to the drive shaft, and pistons reciprocally accommodated in the cylinder bores, characterized in that the assembly structure includes: a swash plate tilt support pin fixedly installed at the drive shaft to cross the drive shaft; a hinge coupling groove formed in the swash plate to be rotatably coupled to a tip of the swash plate tilt support pin in a tilted manner, and a swash plate support part formed in the swash plate to support the drive shaft.Therefore, it is possible to simplify the structure of the swash plate type compressor and reduce its own weight by omitting a lug plate or a hinge mechanism in an assembly structure of the drive shaft and the swash plate.
