Beschreibung
Zusammenfassung:	The outside ring manufacturing method comprises a first step of blanking out from a metal sheet a material with a circular body (17) portion and tongue portions (18) which protrude at several places out of the outer peripheral edge of this body portion, a second step of press forming this material so that the body portion is formed into a tapered cylinder portion (13) which tapers off or decreases in diameter with the distance away from the tongue portions and that the tongue portions are made parallel to an axis of the tapered cylinder portion, a third step of adjsuting the geometry of each part to a fixed value through the machining of an end surface of the tapered cylinder portion (13) and the tongue portions (18), and a fourth step of heat treatment to achieve a desired hardness.
