摘要： A one-way rotational transfer mechanism includes a rotary input shaft; a rotary output shaft provided around the rotary input shaft; a circumferentially-uneven-width-space forming portion formed on the rotary input shaft to form at least one accommodation space having different radial widths at different circumferential positions; a differential rotating member installed in the accommodation space, the differential rotating member revolving around the axis of the rotary input shaft in a same direction as a rotational direction of the rotary input shaft while revolving at a slower speed; and a freely movable torque transfer member installed in the accommodation space. The circumferentially-uneven-width-space forming portion is shaped so that the torque transfer member wedges between the circumferentially-uneven-width-space forming portion and an inner peripheral surface of the rotary output shaft to transfer torque from the rotary input shaft to the rotary output shaft.

摘要： A lens barrel includes a distance adjustment ring for moving a movable lens group; a hand-operated ring and a motor for rotating the distance adjustment ring; a one-way rotational transfer mechanism which transfers torque of the hand-operated ring to the distance adjustment ring when the hand-operated ring is manually rotated, and prevents torque of the distance adjustment ring transferring to the hand-operated ring when the distance adjustment ring is rotated by the motor. A circumferentially-uneven-width-space forming portion formed on an annular overlapping portion of the hand-operated ring, is shaped so that a torque transfer member, installed in an accommodation space between the annular overlapping portion and-a torque transfer cylindrical surface on the distance adjustment ring, wedges between the circumferentially-uneven-width-space forming portion and the torque transfer cylindrical surface to transfer the torque of the manually rotated hand-operated ring to the distance adjustment ring.
