PROBLEM TO BE SOLVED: To reduce man-hours of manufacturing and assembling, in a rolling bearing for a vehicle.SOLUTION: A rolling bearing 10 for a wheel is arranged between an axle tube 2 and a hub wheel 3 possessed by a full-floating type wheel support device 1, and comprises an inner ring 11, an outer ring 12 and conical rollers 13. The inner ring 11 has a pair of divided inner rings 41, 42 which are divided to an inner side and an outer side in an axial direction, and abut on each other. The divided inner rings 41, 42 have recessed peripheral grooves 45, 46 at internal peripheral sides, respectively. Since a connecting member 30 is arranged over a pair of the recessed peripheral grooves 45, 46, the divided inner rings 41, 42 are connected to each other. The connecting member 30 has a connecting ring 34 having a cylinder part 31 and circular ring parts 32, 33, and annular elastic members 38, 39 which are fixed to the circular ring parts 32, 33.SELECTED DRAWING: Figure 1
【課題】車輪用転がり軸受において、製造及び組み立ての工数を低減する。【解決手段】車輪用転がり軸受10は、フルフローティングタイプの車輪支持装置1が有する車軸管2とハブ輪3との間に設けられ、内輪11、外輪12、及び円すいころ13を備えている。内輪11は、軸方向インナ側とアウタ側とに分割され軸方向に突き合わされている一対の分割内輪41,42を有している。分割内輪41,42それぞれは、内周側に凹周溝45,46を有している。一対の凹周溝45,46に跨って連結部材30が設けられることで分割内輪41,42が連結されている。連結部材30は、円筒部31及び円環部32,33を有する連結用リング34と、円環部32,33に固定されている環状弾性部材38,39とを有している。【選択図】 図1
