Claims

[Claims for Utility Model Registration] The circumferential surface of the driven disk 5B, on which the elastic ring 9 is fitted on the outer periphery, is pressed against the plate surface of the drive disk 5A in such a manner that its position can be changed and fixed in the direction of the rotation radius. In the friction transmission type continuously variable transmission, a fitting portion 5 having an L-shaped vertical cross section into which the elastic ring 9 can be fitted to the outer circumferential portion of the rotating body 5b of the driven disk 5B from the axial direction of the driven disk 5B.
b' is integrally formed, and the L-shaped fitting part 5
a removable backing plate 10 located opposite b' and preventing the elastic ring 9 from coming off in the axial direction;
, the elastic ring 9 is attached detachably and replaceably from the axial direction, and the driven disk 5 is attached to the driven disk 5.
A detent mechanism 13 is provided to prevent relative rotation of the elastic ring 9 with respect to the rotary body 5b of the driven disk 5B, and an L integrally formed with the rotary body 5b of the driven disk 5B is provided.
A friction transmission type stepless device characterized in that the fitting portion 5b' of the mold is located radially outward of the drive disk 5A in the normal operating area of the driven disk 5B with respect to the drive disk 5A. gearbox. The rotation prevention mechanism 13 is configured to form an occlusion between circumferential wave-shaped teeth 14 formed on the circumferential surface of the fitting portion 5b' of the rotating body 5b and circumferential wave-shaped teeth 15 formed on the inner circumferential surface of the elastic ring 9. A friction transmission type continuously variable transmission according to claim 1, characterized in that the friction transmission type continuously variable transmission is constructed as follows.
