Abstract
A housing for a fluid lubrication bearing apparatus is produced. The housing has a cylindrical shape whose inner periphery having a fixing face to which an outer circumferential surface of a bearing sleeve is to be fixed. The method includes providing a forging mold having a groove molding portion extending parallel to a direction of a stroke of said mold and a face molding portion having a convex cylindrical shape on an outer periphery of the forging mold for forming the fixing face of the housing. The method further includes forming the housing with the forging mold, while forging circulation grooves and the fixing face simultaneously on the inner periphery of the housing with the groove molding portion and the face molding portion of the forging mold.
