Abstract
A scroll type compressor having a main frame, a sub frame and a crankshaft rotatably mounted in the main frame and the sub frame via a main frame bushing and a sub frame bushing, further includes a fixed scroll and an orbiting scroll cooperable with the fixed scroll to compress gas, the orbiting scroll being drivingly mounted on the eccentric shaft portion. A barrel shaped band portion faces the crankshaft and presents a convex surface in at least one of a respective force direction of a compressive load generated in a compression chamber formed between the orbiting scroll and the fixed scroll, and a reactive force direction of a centrifugal load generated by a revolution movement of the orbiting scroll and rotary movements of upper and lower balance weights. The barrel shaped band portion is formed on the sub frame bushing.
