ABSTRACT:
A friction roller type continuously variable transmission comprises input and output discs arranged on a common axis; friction rollers each being operatively interposed between the input and output discs to transmit torque therebetween; supporting members each rotatably supporting the friction roller and having a shaft extending therefrom; servo-pistons each including a hollow boss portion which has the shaft of the corresponding supporting member slidably received therein, the hollow boss portion being capable of pushing the corresponding supporting member to pivot the corresponding friction roller to continuously change a speed ratio between the input and output discs; and links each connecting corresponding ends of the supporting members to suppress displacement of each friction roller which would occur when the friction roller is applied with a certain thrust from the input and output discs. Articulated structures are provided each being arranged between the hollow boss portion and the corresponding supporting member to permit a pivotal movement of the supporting member relative to the hollow boss portion. Positioning structures are further provided each effecting a relative rotational positioning between the supporting member and the corresponding hollow boss portion.
