<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device capable of exercising superior creep-preventing performance by relieving expansion and contraction of a shaft due to temperature change, and facilitating its mounting and demounting work. <P>SOLUTION: This rolling bearing device 30 comprises a rolling bearing 9 having an inner ring 11, an outer ring 12 having a notch portion 12d over an outer peripheral face 12a and an axial end face 12b, and a plurality of rolling elements 13 rollably disposed between the inner ring 11 and the outer ring 12, a creep-preventing member 21 mounted in opposition to the axial end face 12b of the outer ring 12, and kept into contact with the axial end face 12b so that it can be advanced to the notch portion 12d when the notch portion 12d and a circumferential phase are agreed with each other, and an elastic member 22 for energizing the creep-preventing member 21 toward the axial end face 12b of the outer ring 12. <P>COPYRIGHT: (C)2007,JPO&INPIT |
