There is provided a rolling bearing which comprises at least: an outer ringand an inner ringdisposed rotatable relative to each other; and plurality of rolling elementsrespectively interposed rollably between the outer and inner rings. The outer ring is fitted into a housing (not shown) and the inner ring is fitted with a shaft (not shown), whereby the rolling bearing supports rotation between the shaft and housing. Between the fitting surface (not shown) of the housing and the outer circumferential surfaceof the outer ring and/or between the fitting surface of the shaft and the inner circumferential surfaceof the inner ring, there is interposed an O-ringmade of an elastic member having a reduced friction coefficient between the fitting surface of the housing and the outer circumferential surface of the outer ring or between the fitting surface of the shaft and the inner circumferential surface of the inner ring.
