Claims

[Scope of utility model registration request]

A fixed scroll and an oscillating scroll, each having a spiral protrusion on its base plate, which form a compression chamber by combining the volute protrusions with each other, and an oscillating scroll that is eccentrically supported at the upper end and whose lower end is immersed in lubricating oil. A main shaft, a bracket that rotatably supports the main shaft at the bottom of the oscillating scroll, a thrust bearing provided between the base plate of the oscillating scroll and the bracket, an electric motor that rotationally drives the main shaft, and an eccentric support for the main shaft. In a scroll compressor equipped with an eccentric oil supply hole provided through the thrust bearing, the thrust bearing is provided with an oil groove extending from the inner circumferential end halfway in the outer circumferential direction and an oil return hole communicating with the oil groove on the upper surface of the thrust bearing. The bracket is provided with an oil return hole at a position corresponding to the oil return hole, and the thrust bearing is fastened and fixed to the bracket by inserting a hollow spring pin into the oil return hole and the oil return hole. scroll compressor.
