<p>PROBLEM TO BE SOLVED: To precisely correct displacement of a center of gravity to a rotation center of a movable scroll having a stepped part and a step part in a scroll type compressor.SOLUTION: In a movable scroll 20 constituting a scroll type compressor, a spiral wall correction part 88 is formed on an outer peripheral side of a second movable side wall part 84 of a movable side spiral wall 62, and an end plate correction part 70 is formed on an outer peripheral side of a movable side end plate 60. The end plate correction part 70 is recessed on an outer periphery by predetermined depth within a range that does not contribute to a gas compression chamber formed between the movable scroll 20 and a stationary scroll 18, and at a position on the outer peripheral side of a first movable side bottom face part 64. Then, ranges and depths of the spiral wall correction part 88 and the end plate correction part 70 are adjusted according to a gravity center position of the movable scroll 20, so that the gravity center position is corrected to be coincident with a rotation center of the movable scroll 20.</p> |
