Abstract
A wheel bearing apparatus incorporating a rotational speed detecting apparatus has a protecting cover. A cylindrical fitting portion of the cover is press-fit into the end inner circumference of the outer member. A donut-shaped shielding portion extends radially inward from the fitting portion, via a radially reducing portion. A bottom portion is continuous with the shielding portion, via a stepped portion, to close the inner-side end of the inner member. A sealing member is integrally adhered to the outer circumference of the radially reducing portion. The sealing member and annular portion has a diameter slightly smaller than the outer diameter of the fitting portion of the protecting cover. The sealing member projected portion has a diameter slightly larger than the outer diameter of the fitting portion of the protecting cover. The projected portion is press-fit into the end inner circumference of the outer member via a predetermined interference.
