To provide a rolling bearing device capable of improving workability in assembly work.SOLUTION: A rolling bearing device comprises: an outer ring 17; a pair of inner rings 18a, 18b; rolling bodies 19a, 19b; and a connection ring 20 that is formed in the shape of a broken ring having a discontinuous part at one location in a circumferential direction as a whole, has a pair of locking parts 33 on both side parts in an axial direction, and connects the pair of inner rings 18a, 18b by locking the pair of locking parts 33 to locking concave grooves 25a, 25b of the pair of inner rings 18a, 18b. The connection ring 20 has a configuration in which both end parts in the circumferential direction are arranged so as to overlap each other in the axial direction in a free state.SELECTED DRAWING: Figure 2
【課題】組立作業の作業性を向上させることができる転がり軸受装置を提供する。【解決手段】外輪17と、1対の内輪18a、18bと、転動体19a、19bと、全体として周方向1箇所に不連続部を有する欠円環状に構成され、かつ、軸方向両側部に1対の係止部33を有し、1対の前記係止部33を1対の内輪18a、18bの係止凹溝25a、25bに係止することにより、1対の内輪18a、18bを連結する連結環20とを備える。連結環20は、自由状態で、周方向両側の端部が互いに軸方向に重畳して配置される構成を有する。【選択図】図2
