た請求項１記載のスクロール流体機械。[Claims for Utility Model Registration] 1. A fixed scroll that forms a first wrap in a concave space surrounded by a peripheral wall provided with a port that functions as an inlet or an outlet; and a fixed scroll that fits into the first wrap. and an orbiting scroll having a possible second lap, and by causing the orbiting scroll to revolve around the fixed scroll without rotating on its own axis, the volume of the sealed space formed between the two laps is increased from the peripheral area to the central area. In a scroll fluid machine configured to be gradually contractible as the wrap progresses, a substantially involute-shaped sealing element is formed from a plurality of members to fit into the axial end face of the wrap and seal the facing sliding surface side, A scroll fluid machine characterized in that at least one of the members is made of a material different from that of the other members. 2. The scroll fluid machine according to claim 1, wherein the plurality of sealing elements are fitted into one groove provided in the axial end face of the wrap in a substantially connected state without being separated. 3. In a scroll compressor that has a suction port on the peripheral wall side of a fixed scroll and a discharge port on the center area side,
The plurality of sealing elements are fitted into one concave groove provided on the axial end surface of the wrap in a substantially continuous state without being separated, and at least one groove located on the central area side thereof is fitted. 2. The scroll fluid machine according to claim 1, wherein the sealing element is formed of a material having a lower coefficient of thermal expansion and/or a material having higher wear resistance than other sealing elements located on the peripheral side.
