Scroll compressor and method for producing eccentric bush necessary for scroll compressor

A scroll compressor comprising:

• a shaft rotated by a drive source;
• an eccentric bush having a recess, into which the shaft is inserted, and an eccentric portion eccentric to the shaft;
• an orbiting scroll performing an orbiting motion in cooperation with the eccentric portion;
• and
• a fixed scroll engaged with the orbiting scroll, wherein the eccentric bush further comprises pore apertures.

A method for producing an eccentric bush required for a scroll compressor comprising a shaft rotated by a drive source;

• an eccentric bush having a recess, into which the shaft is inserted, and an eccentric portion eccentric to the shaft;
• an orbiting scroll performing an orbiting motion in cooperation with the eccentric portion;
• and a fixed scroll engaged with the orbiting scroll, the method comprising steps of:
• mixing a powder required for the eccentric bush of the scroll compressor,
• compacting the powder having undergone the mixing;
• sintering a shaped article having undergone the compacting;
• and
• sizing a sintered article having undergone the sintering by compressing the sintered article.
