Abstract
A scroll compressor includes: a shell forming an outer case, a fixed scroll and an orbiting scroll stored in the shell, a frame holding the orbiting scroll, a thrust plate between the orbiting scroll and the frame, and a thrust oil return pipe fixed to the frame. The shell forms an oil reservoir in which lubricating oil is reserved. The orbiting scroll and fixed scroll form a compression chamber. Lubricating oil flows through the thrust oil return pipe to return to the oil reservoir. A hole portion on the thrust plate passes from a first surface portion that slidably contacts the orbiting scroll to a second surface portion facing the frame. The thrust oil return pipe is inserted into the hole portion and fits in the thrust plate. An upper end portion of the thrust oil return pipe does not protrude from the first surface portion of the thrust plate
