<p>One object of the present invention is to provide a wheel bearing apparatus which can prevent generation of corrosion with improving the sealability between the outer member and the knuckle as well as ensure the sealing property for a long term with improving the muddy water resistance. According to the present invention there is provided a wheel bearing apparatus for a vehicle characterized in that the inner-side seal of the seals comprises an annular slinger and a sealing plate, the slinger comprising a cylindrical portion to be press-fitted onto the inner member and standing portion extending radially outward from the cylindrical portion, and the sealing plate comprising a core metal to be press-fitted into the inner circumference of the end of the outer member and a sealing member integrally adhered to the core metal via vulcanizing adhesion and having a pair of side lips angularly extending radially outward and adapted to be slide-contacted with the standing portion of the slinger via a predetermined axial interface; that the sealing member is secured to the core metal with extending over the outer circumference of the end of the core metal; and that the sealing member is formed with an outer circumferential lip extending radially outward from its circumferential end, having a substantially L-shaped longitudinal section and adapted to be fitted in a gap between the inner-side end of the outer member and a flange portion of the knuckle.</p> |
