The present invention relates to a bearing device for a wheel, capable of easily discharging a foreign matter, such as muddy water, to the outside of a sealing device. According to the present invention, the bearing device for a wheel comprises an outer wheel (12), an inner shaft member (11), a rolling element (13), a case (14), and the sealing device (16). The sealing device (16) comprises an annular slinger (21) and a sealing member (22). The slinger (21) has a first inclined surface (33) provided on an outer side in a radial direction and a side facing the sealing member (22), and the diameter of the first inclined surface (33) is gradually increased toward a first side of an axial direction. The sealing member (22) has a second inclined surface (37) provided on an outer side in a radial direction and a side facing the slinger (21), and the diameter of the second inclined surface (37) is gradually increased toward a second side in an axial direction. The second inclined surface (37) crosses a virtual extension surface outwardly extended in the radial direction along the first inclined surface (33) and is continued to the inner circumferential surface of an outer part (40) in the radial direction.

    차륜용 베어링 장치는 외륜(12), 내부 축 부재(11), 롤링 요소(13), 케이지(14) 및 밀봉 장치(16)를 포함한다. 상기 밀봉 장치(16)는 환형 슬링거(21) 및 밀봉 부재(22)를 포함한다. 상기 슬링거(21)는 반경 방향 외측 및 상기 밀봉 부재(22)에 대향하는 측상에 제공된 제1 경사 표면(33)을 갖고, 제1 경사 표면(33)의 직경은 축방향의 제1 측을 향해 증가한다. 상기 밀봉 부재(22)는 반경 방향 외측 및 상기 슬링거(21)에 대향하는 측상에 제공된 제2 경사 표면(37)을 갖고, 제2 경사 표면(37)의 직경은 축방향의 제2 측을 향해 증가한다. 상기 제2 경사 표면(37)은 상기 제1 경사 표면(33)을 따라 반경 방향 외향으로 연장하는 가상 연장 표면과 교차하고, 상기 제2 경사 표면(37)은 반경 방향 외측부(40)의 내부 주연 표면에 이어져있다.
