きとなることを特徴とする回転体保持機構。[Claims for Utility Model Registration] A plurality of balls are interposed in the circumferential direction between the inner member and the outer member, and one of the inner member and the outer member is a rotating body relative to the other. In the rotating body holding mechanism configured to rotatably hold the rotating body, the first ball holder is formed on the inner member and abuts a part of each ball at a position diagonally above and below the center of each ball. and the first ball receiver is formed on the outer member to face the part, and the first ball receiver is arranged to abut a part of each ball at an obliquely up and down position that is symmetrical to the above-mentioned up and down positions with respect to the center of each of the balls. contact,
The second ball holder is configured to sandwich the ball between the first ball holder and the second ball holder, and the pressing force parallel to the axis of rotation of the rotating body is applied to the first and second ball holders. A rotary body holding mechanism characterized in that the ball receiver divides pressure in the radial direction of the rotary body between the part and each ball, and the rotation plane of each of the balls is oriented parallel to the rotation axis of the rotary body. .
