    摘要: Object: In a scroll type fluid machine in which a swivel scroll (14) is driven by a drive bush (101) engaged with a drive shaft bearing portion of said swivel scroll (14) and an eccentric drive pin (25) provided eccentrically on a drive shaft (7), a concentrated surface fatigue caused on the surface of the drive bush (101) is avoided and an elongation of the life of the drive bush (101) is attained.
    Construction: A rotatable cylindrical ring (102) is provided on the outer circumference of the drive bush (101).
