Zusammenfassung:	To improve compression efficiency of a scroll compressor.SOLUTION: An oil return hole 55 has an opening 55h that opens inside a recess 52, and the opening 55h is not closed by a swirling spiral wall 26b when a swirling scroll 26 revolves. According to this, oil returned to a compression chamber 27 from the oil return hole 55 efficiently flows toward the compression chamber 27. Therefore, a space between a fixed scroll 25 and the swirling scroll 26 is sealed by oil, so that the compression chamber 27 has excellent sealability.SELECTED DRAWING: Figure 4 【課題】スクロール型圧縮機の圧縮効率を向上させること。【解決手段】オイル戻し孔５５は、凹部５２の内側に開口する開口５５ｈを有し、開口５５ｈは、旋回スクロール２６の公転時に旋回渦巻壁２６ｂによって閉塞されない。これによれば、オイル戻し孔５５から圧縮室２７へ戻されるオイルが、圧縮室２７に向けて効率良く流れる。このため、固定スクロール２５と旋回スクロール２６との間がオイルによってシールされることで、圧縮室２７の密閉性が良好なものとなる。【選択図】図４
