Abstract
In a fixing structure for a rolling bearing in which a bearing fixing ring is incorporated in a device and a rotating member is fixed to a bearing rotating ring using bolts, fastening areas with the bolts are set so that the natural frequency of the device as a whole is larger than the frequency of vibration resulting from the rotation of the rolling bearing. This prevents generation of noise or vibration in the rolling bearing.
