<P>PROBLEM TO BE SOLVED: To provide a scroll type compressor in which local wear is reduced in an eccentric mechanism. <P>SOLUTION: The scroll type compressor includes: a fixed scroll (not shown) configured in a spiral shape; a movable scroll (not shown) which is configured in a spiral shape likewise and is arranged so as to be opposed to the fixed scroll; and a shaft 4 which causes the movable scroll to turn, and includes a first protrusion part 4a eccentric to the rotation center and a second protrusion part 4b on the position corresponding to the first protrusion part 4a, wherein the shaft 4 is engaged with the movable scroll 2 via an eccentric bush 5 with which the first protrusion part 4a and the second protrusion part 4b are engaged through clearances, the clearance that is set for the second protrusion part 4b being larger than the clearance set for the first protrusion part 4a, and wherein the movable scroll is caused to turn by changing the turning radius by the clearance disposed on the second protrusion part 4b around the first protrusion part 4a. In the scroll type compressor, the first protrusion part 4a is configured in a polygonal shape, and the contacting of the first protrusion parts 4a with the eccentric bush 5 can be configured at multi points and, as a result, loading points can be dispersed and the local wear can be avoided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
