    摘要： A fluid lubrication bearing apparatus which can stably produce high bearing performance is provided at low costs. Moreover, a method for producing a housing for hydrodynamic bearing apparatuses which can improve the accuracy of form of the housing of this type at low costs is provided.In forming a housing 7 which has a cylindrical shape and comprises a fixing face 7c for fixing the outer circumferential surface 8b of a bearing sleeve 8, and axial circulation grooves 7d for bringing both end faces 8c, Sd of the bearing sleeve 8 into circulation on the inner periphery by forging, a groove molding portion 18a2 is provided on the outer circumference of a rod 18 which serves as a forming mold for the inner periphery of the housing 7, and the circulation grooves 7d are formed by forging with this groove molding portion 18a2. Moreover, after a sealing face 107d and a cylindrical outer circumferential surface 107e provided on the outer periphery of the housing 107 are formed by forging, an inner circumferential surface 107c is formed by forging. Accordingly, the thrust bearing face 107a is finished to have the perpendicularity with respect to the inner circumferential surface 107c or outer circumferential surface 107e of 20 Mm or less. Moreover, the sealing face 107d is finished to have the coaxiality with respect to the inner circumferential surface 107c or outer circumferential surface 107e of 20 p.m or less. Moreover, the outer circumferential surface 107e is finished to have the coaxiality with respect to the inner circumferential surface 107c of 20 p.m or less.
