PROBLEM TO BE SOLVED: To reduce a force necessary for diameter-contracting a snap ring 20a.SOLUTION: An axial single end face of a snap ring 20a is formed into an inclined face 29 which is inclined to a direction in which an inside diameter becomes smaller as progressing toward an axial other end. A portion shifted to the axial other end of a pinion shaft 6 is made to penetrate the snap ring 20a in a state that the axial single end face of an inner ring 17 abuts on an inside-diameter side stepped face arranged at a middle of the pinion shaft 6. Then, the portion shifted to the axial other end of the pinion shaft 6 is made to penetrate a caulking tool 31 which is arranged at an inclined face part 30 which is inclined to a direction in which the inside diameter becomes smaller as progressing toward the axial other end at an internal peripheral face, and the caulking tool 31 is pressed against an axial single side.

    【課題】止め輪20aを縮径するのに要する力の低減を図る。【解決手段】この止め輪20aの軸方向片端面を、軸方向他側に向かうに従って内径が小さくなる方向に傾斜した傾斜面29とする。ピニオン軸6の中間部に設けた内径側段差面に、内輪17の軸方向片端面を突き当てた状態で、このピニオン軸6の軸方向他端寄り部分を前記止め輪20aに挿通する。そして、このピニオン軸6の軸方向他端寄り部分を、内周面に軸方向他側に向かう程内径が小さくなる方向に傾斜した傾斜面部30を設けたかしめ工具31に挿通し、このかしめ工具31を軸方向片側に向け押圧する。【選択図】図1
