PROBLEM TO BE SOLVED: To provide a new means capable of preventing intrusion of a foreign matter when handling rolling bearings eyen if the rolling bearings are narrow such as being unable to block up respective openings of shaft directional both end parts of one rolling bearing. SOLUTION: A plurality-bearing integrated bearing device is formed by integrally holding a plurality of rolling bearings 2 and 2 by a holder 3 by axially juxtaposing the plurality of rolling bearings 2 and 2 having an inner race 7 and an outer race 6 as bearing rings of a rolling body 5. The holder 3 integrally holds a plurality of bearing rings 6 and 6 of either one of the inner race 7 or the outer race 6 among the bearing rings, and do not contact with the other bearing ring 7. The holder 3 has shield parts 12 and 15 for blocking up end part openings 16a and 16d unadjacent to the other rolling bearing among shaft directional end part openings 16a, 16b, 16c, and 16d between the inner-outer bearing rings 6 and 7 of the rolling bearing 2.
