To provide a rolling bearing device capable of preventing a connection ring from falling from a locking recessed groove provided in an inner ring outside in the axial direction, during assembly work to a support shaft.SOLUTION: A connection ring 21 includes: a plurality of opening windows 36; and a plurality of locking protrusion parts 37a, 37b formed on both side parts in the axial direction of an opening edge part of the plurality of opening windows 36 and locked in locking recessed grooves 26a, 26b of inner rings 19a, 19b. The locking protrusion parts 37a, 37b have a bulging shape, and have pressing surfaces 38a, 38b including a shear surface 40. An end part radially outside of the shear surface 40 is positioned radially outside with respect an end part radially outside of chamfer parts 28a, 28b provided at surfaces 27a, 27b to be pressed of the locking recessed grooves 26a, 26b, and the shear surface 40 is brought into contact with a radially outside portion with respect to the chamfer parts 28a, 28b out of the surfaces 27a, 27b to be pressed.SELECTED DRAWING: Figure 3
【課題】支持軸への組み付け作業時に、軸方向外側の内輪に備えられた係止凹溝から連結環が脱落するのを防止できる、転がり軸受装置を提供する。【解決手段】連結環21を、複数の開口窓36と、複数の開口窓36の開口縁部の軸方向両側部に形成された、内輪19a、19bの係止凹溝26a、26bに係止される複数の係止凸部37a、37bとを有するものとする。係止凸部37a、37bを、膨出形状をなし、剪断面40を含む抑え面38a、38bを有するものとする。剪断面40の径方向外側の端部を、係止凹溝26a、26bの被抑え面27a、27bに備えられた面取り部28a、28bの径方向外側の端部よりも径方向外側に位置させ、剪断面40を、被抑え面27a、27bのうちで面取り部28a、28bよりも径方向外側部分に当接させる。【選択図】図3
