ROLLING BEARING DEVICE WITH FIXED PLATE

To prevent the deterioration of the roundness of an outer ring by dispersing a pressing force applied to the outer ring by a fixed plate in a circumferential direction of the outer ring, and applying the pressing force to the outer ring as a whole.SOLUTION: A rolling bearing device with a fixed plate comprises an outer ring 21, an inner ring 23, balls 25 assembled between the outer ring 21 and the inner ring 23, and the fixed plate 3 fixed to the outer ring 21. The fixed plate 3 has an outer ring fitting part 3a fixed to the outer ring 21, and having a constant width in a radial direction, and an attachment part 3b arranged at an outside diameter rather than the outer ring fitting part 3a, and attached to a fixing object. The attachment part 3b includes a screw hole 31 into which a fastening member for fastening the fixed plate 3 and the fixing object is inserted, and a slit 32 which is overlapped on the screw hole 31 in a peripheral direction, and formed with an interval at a side in the radial direction rather than the outer ring fitting part 3a.SELECTED DRAWING: Figure 1 【課題】 固定板により外輪に加わる押圧力を外輪の円周方向で分散させ、押圧力を外輪全体に加わるようにして、外輪の真円度の悪化を防止する。【解決手段】 固定板付転がり軸受装置は、外輪２１と、内輪２３と、外輪２１と内輪２３との間に組み込まれるボール２５と、前記外輪２１に固定される固定板３と、を備え、固定板３は、外輪２１に嵌合されて径方向に一定の幅を有する外輪嵌合部３ａと、外輪嵌合部３ａよりも外径に設けられて固定対象物に取り付けられる取付部３ｂとを有し、取付部３ｂは、固定板３と固定対象物とを締結する締結部材が挿通されるねじ孔３１と、ねじ孔３１と周方向に重なると共に外輪嵌合部３ａよりも径方向側に間隔を設けて形成されたスリット３２とを含んでいる。【選択図】 図１
