Claims

[Claims for Utility Model Registration] A fixed scroll housed in a housing,
In a scroll type compressor that forms a compression chamber between both scrolls based on relative rotation with a movable scroll that is combined with the fixed scroll and supported so as to be non-rotatable and rotatable, the scroll is fixed to the base end wall of the movable scroll. Circular revolution position regulation holes that align with each other are provided in the fixed ring fixed to the fixed base plate facing the base end wall, and each revolution position regulation hole has a diameter necessary for regulation. A scroll compressor characterized in that a cylindrical bearing element is interposed therein and relief grooves communicating with each revolution position regulating hole are formed on the back surfaces of both rings.
