<p>PROBLEM TO BE SOLVED: To provide a bearing fixing structure capable of reducing an increase in hoop stress generated in a bearing inner ring by suppressing the occurrence of force in a direction to increase the diameter of the bearing inner ring when a caulking ring is caulked to fix a bearing to a shaft.SOLUTION: A bearing fixing structure is to fix a bearing by caulking a cylindrical caulking ring into an annular groove formed on a shaft. The caulking ring has a one-end-side end face opposed to an inner ring end face of the bearing. The groove has an engaging face opposed to the one-end-side end face. The one-end-side end face of the caulking ring is in contact with both the inner ring end face of the bearing and the engaging face of the groove.</p> |
