体機械。[Claims for Utility Model Registration] 1. A scroll that includes a spiral groove extending substantially along the center line of the end face of the wrap facing the sliding surface of the other scroll, and a tip seal that is fitted into the groove. In a fluid machine, a spiral groove section has a wedge-shaped projection formed between two imaginary circles that are shifted in the spiral direction by a distance smaller than the diameter of the groove, and a recess corresponding to the wedge-shaped projection. It consists of a combination of chip seals made of a self-lubricating resin material formed into a band shape without any provision, and is characterized in that by fitting the chip seal into the groove, the chip seal is held under pressure while being deformed by the wedge-shaped protrusion. Scroll fluid machine. 2. The compressor functions as the compressor according to claim 1, wherein the two virtual circles forming the wedge-shaped projections have diameters that substantially correspond to the width of the groove, and the wedge-shaped projections are formed on both side wall surfaces of the groove in the center area. Scroll fluid machine.
