Abstract

The present invention addresses the problem of suppressing movement of a slinger in an axial direction regardless of the resultant axial length of a cylindrical part of the slinger. An outer-side seal member (10) of a wheel bearing device (1) comprises: a slinger (13) that is provided to a base part (3d) of a hub flange (3b) and that has a cylindrical part (13a) which fits into an outer peripheral surface (3j) of a hub ring (3) and a disk part (13b) which faces the hub flange (3b); and a seal member (12) that has a seal lip. The outer peripheral surface (3j) of the hub ring (3) has a fitting part (31) into which the cylindrical part (13a) of the slinger (13) fits. The fitting part (31) has a small-diameter section (311) and a large-diameter section (312) that is positioned farther from the hub flange (3b) than the small-diameter section (311) in the axial direction and that is formed to have a diameter larger than that of the small-diameter section (311).
