ABSTRACT:
A sealing device for a water pump bearing employs a seal member without an axial lip, and having only a radial lip. The sealing device includes an annular seal member which is fixed to a shoulder portion of one end in an axial direction of an outer race of a water pump bearing and an annular slinger which is positioned on a side of the one end in the axial direction with respect to the seal member and externally fixed to the outer peripheral face of a pump shaft serving as an inner race. The seal member has a section shape which is bent along a disk portion and an outer cylindrical portion of the slinger. A labyrinth seal portion is formed between the seal member, and the disk portion and the outer cylindrical portion of the slinger. Radial lips are formed on an inner periphery of the seal member.
