Zusammenfassung:To provide a scroll compressor whose lubrication performance is further improved.SOLUTION: A scroll compressor comprises an electric motor, a rotating shaft to be rotated around an axis extending in a horizontal direction, a bearing part for supporting the rotating shaft, a turning scroll to be turned around the axis, a fixed scroll for forming a compression chamber by being opposed to the turning scroll, a rotation prevention mechanism provided in the turning scroll, and an oil supply passage capable of supplying lubricating oil to the rotation prevention mechanism. The rotation prevention mechanism comprises a circular guide concave part formed in a back surface of the turning scroll, and a pin inserted into the guide concave part, and for guiding the turning of the turning scroll by being in contact with an inner peripheral surface of the guide concave part. The oil supply passage comprises a supply hole formed in the bearing part, and to be made to face the guide concave part in association with the turning of the turning scroll.SELECTED DRAWING: Figure 2 【課題】潤滑性能がさらに向上したスクロール圧縮機を提供する。【解決手段】スクロール圧縮機は、電動機と、水平方向に延びる軸線回りに回転する回転軸と、回転軸を支持する軸受部と、軸線を中心として旋回する旋回スクロールと、旋回スクロールに対向することで圧縮室を形成する固定スクロールと、旋回スクロールに設けられた自転防止機構と、自転防止機構に潤滑油を供給可能な油供給流路と、を備え、自転防止機構は、旋回スクロールの裏面に形成された円形の案内凹部と、案内凹部に挿入され、案内凹部の内周面に当接することで旋回スクロールの旋回を案内するピンと、を有し、油供給流路は、軸受部に形成されるとともに、旋回スクロールの旋回に伴って案内凹部を臨む供給孔を有する。【選択図】図2
