IPC: F16D41/07

Abstract: An object of the present invention is to provide a cam clutch that biases cams with a stable force and enables improvement in durability and operational stability. The biasing means for biasing the cams to contact the inner race and outer race is formed by a ribbon spring, with a base part shaped into a ring and having cam-receiving portions and cam-biasing portions. The ribbon spring has an end structure configured to allow both ends of the base part to push each other in a circumferential direction. The end structure is configured to include a contact portion that extends in a radial direction and makes surface-contact with any of the inner race, the outer race, and the cage ring that holds the cams.
