Zusammenfassung:PROBLEM TO BE SOLVED: To dispense with a correction work for a shaft hole of an inner shaft in assembling a shaft body to the shaft hole of the inner shaft. SOLUTION: This roller bearing device A is assembled by spline-engaging the shaft part (the shaft body) 7a of a universal joint 7 with the shaft hole 2d of the inner shaft 2. The inner peripheral surface of the shaft hole 2d is formed substantially like a conical face having a first gradient α extending from the shaft hole inlet d1 side to the shaft hole outlet d2 side. The shaft part 7a formed substantially like a conical face and having a second gradient α2(≥α1) is inserted in the shaft hole 2d. A nut 8 engaged with the end part 7c of the shaft part 7a is fastened to the end face 2e of the inner ring 2. COPYRIGHT: (C)2005,JPO&NCIPI
