Abstract
The invention disclosed herein provides reduced cost for manufacturing a swing arm for magnetic disc. The swing arm for magnetic disc comprises a plurality of arm members, the arm members comprising a top arm member, at least one or more intermediate arm members, and a lower arm member. Each of the arm members includes a cylindrical portion having large diameter upper and small diameter lower cylindrical portions. The cylindrical portions of the intermediate, and lower arm members include a fitting hole, in which a bearing device is fitted for supporting a spindle, the fitting holes comprising a large diameter bore, and a small bore into which the bearing is fit, respectively. The small diameter cylindrical portions of the top, and intermediate arm members are fitted into the large diameter hole of the intermediate arm members, and the lower arm members, respectively. Thereby, the arm members are connected with each other so that a swing arm for magnetic disc is formed in integrally forming relation of them.
