Summary:To provide a rolling bearing device for a wheel, in which the occurrence of abnormal sound can be suppressed using a part of a slinger and the co-rotation of the slinger with a joint can be suppressed.SOLUTION: An inward member 12 has an axial end which is pushed to the other axial side by a cup portion 51. A hermetically sealing device 15 has a slinger 31 mounted to the inward member 12, and a sealing member 32 mounted to an outward member 11. The slinger 31 has a slinger main body 34 fitted and mounted to part of the inward member 12, and an extending portion 35 extending radially inward from the slinger main body 34 and interposed between the axial end and a cup portion 51. The extending portion 35 has a first face 36 contacting the axial end and a second face 37 contacting the cup portion 51 and having a small friction coefficient between the cup portion 51 and itself. At a mounting portion 20 between the slinger 31 and the inward member 12, a detent 40 is provided for suppressing relative rotation displacement between the inward member 12 and the slinger 31.SELECTED DRAWING: Figure 1 【課題】車輪用転がり軸受装置において、スリンガの一部を用いて異音の発生を抑えることを可能とすると共に、スリンガが継手と供回りすることを抑制する。【解決手段】内方部材１２は、カップ部５１によって軸方向他方側に押される軸方向端部を有する。密封装置１５は、内方部材１２に取り付けられたスリンガ３１と、外方部材１１に取り付けられたシール部材３２とを有する。スリンガ３１は、内方部材１２の一部に嵌合して取り付けられたスリンガ本体３４と、スリンガ本体３４から径方向内方に延び前記軸方向端部とカップ部５１との間に介在する延在部３５とを有する。延在部３５は、前記軸方向端部と接触する第一面３６と、カップ部５１と接触すると共に小さい摩擦係数をカップ部５１との間に有する第二面３７とを有する。スリンガ３１と内方部材１２との取り付け部２０に、内方部材１２とスリンガ３１との相対回転変位を抑制する回り止め部４０を有する。【選択図】 図１
