Description of the Related Art Conventionally, when a ball bearing or the like is mounted on a shaft of a mechanical device, the mounted ball bearing or the like is stopped so as not to move in the axial direction, or is mounted on the shaft end so as not to drop off from the shaft end. As one method of fixing,
An E-shaped retaining ring is mounted on the shaft. In order to mount the E-shaped retaining ring, a groove is provided around the circumference of the shaft, and an E-shaped retaining ring having an opening dimension smaller than the diameter of the groove bottom is used.

はない。[0003] The E-shaped retaining ring is made of spring steel and has strong flexibility. Therefore, the opening is pressed into the groove of the shaft having a diameter larger than the opening dimension, so that the shaft is pressed into the groove. After the attachment, it fits into the groove at three points of the E-shape due to its flexibility, and does not come off unless an extreme external force is applied.
