PROBLEM TO BE SOLVED: To surely supply high-pressure lubricant to a liquid chamber, in a compression mechanism configured to supply high-pressure lubricant from a stationary side oil groove to a movable side oil groove.SOLUTION: A compression mechanism (40) includes: a movable side oil groove (83) in which high-pressure lubricant equivalent to discharge pressure of the compression mechanism (40) is supplied to a portion close to a suction chamber (S1) on a contact surface (A2) of a mirror plate (71) of a movable scroll (70); and a stationary side oil groove (80) in which high-pressure oil equivalent to the discharge pressure of the compression mechanism (40) is supplied to a contact surface (A1) of an outer edge part (63) of a stationary scroll (60), and that is formed so as not to always communicating with the movable side oil groove (83).SELECTED DRAWING: Figure 4 【課題】固定側油溝の高圧の潤滑油を可動側油溝に供給する圧縮機構において、高圧の潤滑油を流体室へ確実に供給できるようにする。【解決手段】圧縮機構（40）では、可動スクロール（70）の鏡板（71）の接触面（A2）における吸入室（S1）寄りの部分に圧縮機構（40）の吐出圧力に相当する高圧の潤滑油が供給される可動側油溝（83）が形成され、固定スクロール（60）の外縁部（63）の接触面（A1）に圧縮機構（40）の吐出圧力に相当する高圧の潤滑油が供給される固定側油溝（80）が、可動側油溝（83）と常に連通しないように形成される。【選択図】図４
