Claims

[Claims for Utility Model Registration] An input shaft and an output shaft are arranged concentrically with each other, and rotational torque applied to the input shaft is transmitted to the output shaft to rotate it. In a one-way rotation transmission device that prevents rotation of the output shaft in response to torque and blocks transmission of rotational torque to the input shaft, flanges are provided at mutually opposing ends of the input shaft and the output shaft, respectively. At the same time, a notch is formed in the flange of the input shaft passing through it in the thickness direction, and the flange end face of the output shaft flange on the input shaft side is parallel to the non-rotating surface of the fixed member with the flange of the input shaft in between. a protrusion that protrudes into the notch is formed on the input shaft side flange end face, and a protrusion that is symmetrical with respect to the direction of the chord passing through the protrusion is formed on the part of the flange end face facing the notch on both sides of the protrusion. and forming flat sloped surfaces that approach the rotational rotation surface as the distance from the protrusion increases, and a diameter smaller than the maximum distance and larger than the minimum distance between each sloped surface and the non-rotation surface. The balls having the protrusion are arranged in the notch so as to sandwich the protrusion, and the balls are urged by a biasing member in a direction away from the protrusion. , by forming a contact surface that selectively brings the ball into contact with the protrusion against the biasing force of the biasing member, the contact surface causes the ball to contact the protrusion when rotational torque is applied to the input shaft. The output shaft is rotated through the balls and protrusions, and when a rotational torque is applied to the output shaft from the output side, the balls bite between the inclined surface and the non-rotating surface and rotate the output shaft. A unidirectional rotation transmission device characterized in that the rotation transmission device is configured to prevent the rotation from occurring.
