摘要： A hub (10) is a product formed by injection molding of a resin together with a core metal (13) as an inserted component, and the core metal (13) is exposed on a surface of the hub (10). With this configuration, a cavity of a die for molding the hub (10) is not divided by the core metal (13), and hence it is possible to suppress deterioration in fluidity of a resin due to arrangement of the core metal (13) in the cavity.

摘要： A shaft portion is press-fitted to a flange portion, and a plastic working portion of a first jig is pressed against an upper end surface of the flange portion, whereby the flange portion is partially subjected to plastic deformation toward an inner peripheral side. With this, a caulked portion is formed between the flange portion and the shaft portion. Further, press-fitting and caulking are performed in a state in which both end surfaces of the flange portion are bound by a second jig and a third jig.

摘要： To provide a fluid dynamic pressure bearing device that achieves high rigidity against moment without degradation in assembly precision and bearing performance, bearing sleeves are arranged in an axial direction and coaxiality of radial bearing surfaces formed on inner peripheral surfaces of the bearing sleeves is set to 3 μm or less. This secures width precision between the radial bearing gaps to prevent a degradation in bearing performance and a failure such as wear etc. caused by contact between a shaft member and the bearing sleeves. Further, a first radial bearing surface and a second radial bearing surface are provided on at least one sleeve, and this allows a sleeve assembly constructed from the bearing sleeves to be supported at least three positions in the axial direction in a process of assembling the sleeve assembly. As a result, assembly work can be carried out with two bearing sleeves prevented from being bent at a midway thereof, and highly accurate coaxiality between both the bearing sleeves is secured.
