Claims (1)

[Claims for Utility Model Registration] A fixed scroll is housed and fixed in a housing, and a movable scroll is housed and supported opposite the fixed scroll so that it cannot rotate on its axis but can revolve around it, and prevents rotation of said movable scroll. As a mechanism for allowing revolution, a plurality of circular recesses are formed in an annular arrangement on the surface opposite to the spiral portion of the movable scroll and on the surface of the fixed substrate opposite thereto, and a roller is arranged between each opposing circular recess. In a scroll type compressor in which the end surfaces of the rollers are in sliding contact with the bottom surfaces of the circular recesses, and the outer peripheral surfaces of the rollers are in contact with the inner peripheral surfaces of the circular recesses, the outer periphery of each roller during compression operation A scroll type compressor, wherein elastic deformation allowing holes are formed in both end surfaces of each roller to elastically deform the roller when an abnormal radial load is applied to the surface by the inner circumferential surface of the circular recess.
