PURPOSE:To make contact pressure variable while make force transmitted to first and second output rings adjustable, by forming a tapered hollow part in a first planetary roller and inserting a second planetary roller into said hollow part. CONSTITUTION:A first output ring 5 which is inscribed in a first planetary roller 3 is provided, and a second output ring 6 the contacting radius of which is different from that of the first output ring 5, is provided on the first planetary roller 3. And, a tapered hollow part is formed in the first planetary roller 3 into which a second planetary roller 4 having a form corresponding to this hollow part is inserted. Due to this construction, contact pressure can be made variable by means of the combination of the first and second planetary rollers 3, 4, while the force transmitted to the first and second output rings 5, 6 can be adjusted. |
