PROBLEM TO BE SOLVED: To solve such a problem that, when an axial load is applied from the outer ring of a bearing to a tapered snap ring, the tapered snap ring plastically deforms the groove shoulder of a snap ring groove and inclines itself, and so the conventional tapered snap ring had come off a housing.SOLUTION: In addition to a tapered snap ring on the bearing side, a tapered snap ring is mounted on the counter bearing side. Thus, even when a material for a housing is aluminum, a material for a groove shoulder can be steel having higher strength, hardly causing plastic deformation. |
