Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rolling bearing for microoscillation and a rolling bearing device with low torque and a less torque fluctuation, improved in high speed and high precision of control, and besides compact at a low cost. SOLUTION: A rolling bearing for microoscillation has a pre-load range of 50-300 gf, and the radius ri of the groove 11m of an inner ring 11, the radius re of the groove 12m of an outer ring 12, and the diameter Da of a ball 13 satisfy a formula of 1
