Abstract
A scroll compressor includes a fixed scroll and a movable scroll. A facing surface of the fixed scroll that faces the movable scroll has a fixed oil groove. The fixed oil groove has a fixed circumferential groove portion. The fixed circumferential groove portion has a circular-arc portion that extends in the circumferential direction, and a wide portion wider in a radial direction than a groove width of the circular-arc portion. A facing surface of the movable scroll that faces the fixed scroll has a movable oil groove. The movable oil groove has a movable circumferential groove portion, and a radial groove portion that communicates with the movable circumferential groove portion. In a predetermined region of an angle range where the movable scroll makes an orbiting motion, a portion of the radial groove portion overlaps the wide portion as viewed from an axial direction.
