Abstract
A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member, an inner member, double row rolling elements, a sensor holder, and a pulser ring. The sensor holder cover has a cylindrical fitting portion press-fit onto the inner side end portion of the outer member. A flange portion extends radially inward from the fitting portion. The flange portion is in close contact with the end face of the outer member. A bottom portion extends further radially inward from the flange portion. The holding portion is integrally joined to the bottom portion. The flange portion is formed with a flat surface so that it forms an abutting width larger than 5 mm or more, against the end face of the outer member, or larger than 50% or more, relative to the flat width of the end face of the outer member.
