PURPOSE:To prevent the inner bore of a bearing device from being tapered by tapering the inner bore of a bearing bush, and press-fitting it in the inner bore of a housing with constant inner and outer diameters. CONSTITUTION:A bearing bush 5 with constant inner and outer diameters is provided on a stopper 1 combined with a die 2, while a core 4 with a head-cut cone shaped main body 4a is inserted in the inner bore 3 of the bearing bush 5, and a bearing bush 5' with a tapered inner bore is thus formed. The bearing bush 5' is press-fitted in a housing with constant inner and outer diameters. A bearing device having an inner diameter with no taper is produced with a synergistic effect of the bearing bush 5' and the housing. |
