Scroll compressor

A scroll compressor, comprising:

• a casing that defines an appearance thereof and has an oil storage space;
• an electromotive part that is installed inside of the casing to generate a drive force;
• a rotational shaft that is rotatably installed in the electromotive part;
• a compression part that comprises an orbiting scroll installed on the rotational shaft to perform an orbital motion, and a fixed scroll engaged with the orbiting scroll to form a compression chamber together with the orbiting scroll;
• and
• a bushing that is disposed between the fixed scroll and the rotational shaft, and coupled to an outer circumference of the rotational shaft to rotate together with the rotational shaft, wherein the bushing is supported by one surface defined inside of the fixed scroll, wherein the bushing comprises an oil supply hole formed such that an inside and an outside of the bushing communicate with each other, wherein the rotational shaft comprises an oil supply opening formed to communicate with the oil supply hole, wherein an oil groove is formed in an inner circumference of the bushing or the outer circumference of the rotational shaft, and wherein the oil groove is formed in a circumferential direction to enable formation of an oil film while oil is accommodated in the oil groove.
