<P>PROBLEM TO BE SOLVED: To obtain a structure allowing the smooth displacement of intermediate rollers 19, 19 with a change in thickness regarding an axial direction of a loading cam device and obtaining excellent transmission efficiency. <P>SOLUTION: A base end of a swing frame 35 with ends of rotating shafts of the respective intermediate rollers 19, 19 rotatably supported is supported to freely be swung and displaced relative to a support frame 32. The intermediate rollers 19, 19 are displaced in a radial direction of the support frame 32 accompanied by the action of the loading cam device. Then, the contact pressure of each traction is made uniform, thus solving the problem. <P>COPYRIGHT: (C)2013,JPO&INPIT |
