A roller bearing assembly apparatus is provided that, when assembling the roller bearing, effectively prevents rollers R that are assembled inside an outer ring W from becoming tilted or dropping out from the state immediately after assembly. After the rollers R are aligned into an annular shape by an alignment jig 14, the roller group G aligned in an annular shape is pushed out from the alignment space 26 of the alignment jig 14, and pushed inside a guide hole 39 of an insertion jig 15. As a result, with the diameter of the roller group G being prevented from expanding by the inner-circumferential surface of the guide hole 39, a retaining member 36, the diameter thereof being elastically reduced, is inserted inside the roller group G. After that, a push-out cylinder 38 of the insertion jig 15 is caused to displace in the axial direction, simultaneously pushing the roller group G and the retaining member 36 out from the guide hole 39, and simultaneously assembling the roller group and the retaining member 36 inside the outer ring W. |
