To provide an assembling method of a shaft member unit which can efficiently assemble the shaft member unit.SOLUTION: In a pressure-insertion process, an internal peripheral tapered part 74 of a pressing head 70 which is driven to a center axial line direction X1 of a shaft member 1 is externally fit and pressure-inserted into the shaft member up to a position at which an inner ring 21 is positioned via a ring 3 without plastically deforming the ring 3 to a diameter-contracted side. In a caulking process, when the internal peripheral tapered part 74 of the pressing head 70 presses the ring 3 to the inner ring 21 side, the internal peripheral tapered part imparts a diameter contraction force not smaller than a plastic deformation load to the ring 3, plastically deforms a part of the ring 3 to the diameter-contracted side, and caulks it to an external peripheral groove 16 of the shaft member 1. The pressure-insertion process and the caulking process are performed by a change of a drive force of a drive part (lift drive part) which drives the pressing head 70.SELECTED DRAWING: Figure 9

    【課題】軸部材ユニットの組立を効率良く行える軸部材ユニットの組立方法を提供する。【解決手段】圧入工程では、軸部材1の中心軸線方向X1に駆動される押圧ヘッド70の内周テーパ部74が、リング3を縮径側に塑性変形させることなく、リング3を介して内輪21を位置決めされる位置まで軸部材1に外嵌圧入する。また、かしめ工程では、押圧ヘッド70の内周テーパ部74が、リング3を内輪21側へ押すときに、リング3に塑性変形荷重以上の縮径力を与えて、リング3の一部を縮径側に塑性変形させて軸部材1の外周溝16にかしめ付ける。押圧ヘッド70を駆動する駆動部(昇降駆動部)の駆動力の変更により圧入工程およびかしめ工程に対応する。【選択図】図9
