摘要： An inner periphery of a molded part having a step from an inner periphery of an electroformed part is molded to a nonconductive coating which covers the surface of a master. When the nonconductive coating is removed, a radial clearance having a diameter greater than that of a bearing clearance is created between the inner periphery of the molded part, which is exposed to the interior, and an outer periphery of a shaft member. A bearing member which forms the bearing and radial clearance with the shaft member is manufactured by performing electroforming on the master with the nonconductive coating formed on part of the surface of the master, thereby forming the electroformed part; then injection molding the bearing member with the electroformed part and the nonconductive coating on the surface of the master inserted into a cavity; and then removing the nonconductive coating from the bearing member.

摘要： Provided is a shaft member for a fluid dynamic bearing device, which is excellent in wear resistance and which can exert a high dynamic pressure effect. A shaft material (11) is rolled to form a recess (7) for causing a dynamic pressure effect of a lubricating oil in a radial bearing clearance (6). In this case, in a surface layer portion (14) of the recess (7) to be formed in an outer peripheral surface (11a) of the shaft material (11), a first hardened layer (14a) is formed by rolling. At the same time, also in a surface layer portion (15) of a surrounding region (8) of the recess (7), a first hardened layer (15a) is formed by rolling at a partial region thereof. After the recess (7) is formed by the rolling, barreling is applied to the shaft material (11). As a result, an outermost surface layer portion of the surface layer portion (15) is formed with a second hardened layer (15b) by the barreling. A hardness of the second hardened layer (15b) formed in the surrounding region (8) is higher by 50 Hv or more and 200 Hv or less than that of the first hardened layer (14a) formed in the recess (7).

摘要： A sliding bearing includes a metal part formed by electroforming on an inner periphery of the sliding bearing and an oil feeding mechanism for supplying oil to the bearing gap. As a result, oil retained by the oil feeding mechanism is supplied to the bearing gap, so the lubricity between the bearing and the shaft member is improved by an oil film formed in the bearing gap. This makes it possible to avoid the generation of noise due to defective lubrication and wear of members due to the contact sliding between the bearing and the shaft member.
