PROBLEM TO BE SOLVED: To solve a problem that slurry flowing along a suspension device such as a knuckle flows out to an external periphery of an outer ring cylinder part of a rolling bearing device for a wheel, a water pouring amount of a sealing device at an outer side is increased by the slurry, and the durability of the sealing device is thereby lowered.SOLUTION: This rolling bearing device 1 for a wheel has an outer ring 2 which is formed of a cylinder part 7 and a plurality of flange parts 8. A cylindrical cylinder face 7a is formed at an outer side rather than the flange parts at an external periphery of the cylinder part 7. A protrusion 32 which protrudes to the outside in a radial direction from the external periphery of the cylinder part 7 at a position in which the protrusion is overlapped on the flange parts 8 in an axial direction being a position in which the protrusion is overlapped on the most apex part of the cylinder face 7a.SELECTED DRAWING: Figure 1

    【課題】 ナックルなどの懸架装置を伝って流れてくる泥水が、車輪用転がり軸受装置の外輪円筒部の外周に流出する。この泥水によってアウター側の密封装置の被水量が増大するので、密封装置の耐久性が低下するという問題がある。【解決手段】 本発明の車輪用転がり軸受装置1は、円筒部7と複数のフランジ部8とからなる外輪2を有している。前記円筒部7の外周には、前記フランジ部よりアウター側に、円筒形状の円筒面7aが形成されている。前記フランジ部8と軸方向に重なる位置で、かつ、前記円筒面7aの最頂部と周方向に重なる位置において、前記円筒部7の外周から径方向外方に突出する凸部32が形成されている。【選択図】図1
