Abstract:
A wheel bearing apparatus has a magnetic encoder  14  mounted on an inner ring  5  opposing the rotational speed sensor  16,  via the cap  10  and an air gap. The cap  10  has a cylindrical fitting part  10 a  press-fit into an inner circumference of an end of the outer member  2.  A shielding part  10 c  extends radially inward from the fitting part  10 a  and has an annular disc shape. A detection part  16 a  of the rotational speed sensor  16  is arranged close to or in contact with a side surface of the shielding part  10 c.  The cap  10  is formed of austenitic stainless steel sheet based on SUS 304. The carbon (C) content is reduced and the nickel (Ni) content is increased. A difference of magnetic flux density between a martensitic transformation part and non-martensite part is 1.4 mT or less.

Claim (Index 4):
The wheel bearing apparatus of  claim 1 , wherein the cap further comprises a radially reduced part, a shielding part, bottom part and cylindrical part, the radially reduced part formed at an end of the fitting part, the shielding part extending radially inward from the radially reduced part, and the bottom part extending from the shielding part via the cylindrical part for closing the inner-side end of the inner member; and wherein a sealing member, of synthetic rubber, is secured on an outer circumference of the radially reduced part, the sealing member comprising an annular part and an annularly projected part projecting radially outward from the annular part, an outer diameter of the annular part being smaller than that of the fitting part of the cap, an outer diameter of the annularly projected part being larger than that of the fitting part of the cap so that the annularly projected part can be pressed against the inner circumference of the outer member.
