Abstract
A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (), formed by combining a plurality of punch elements () divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth () at one end surface in the axial direction, to face the other end surface of the caulking section () in the axial direction. In this state, rolls () are rotated about the central axis (α) of the hub main body () while pressing the other end surface of the forming punch () in the axial direction with a pressing surface () of the roll () having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body ().
