ABSTRACT:
A power input flange is fixed to the tip of a power input shaft whose diameter increases in steps from a tip thereof along a main body thereof and which is supported within a casing, and a power output disk is supported upon the outer peripheral surface of the power input shaft. A power input disk is supported upon the outer peripheral surface of the power input shaft between the power input flange and the power output disk, and a power roller is provided which is contacted at a variable inclination with both the power input disk and the power output disk. A member which biases the power input disk in the direction of the power output disk is supported upon the power input flange. And the power input flange is supported via a radial bearing upon the outer peripheral surface of a tubular shaped support portion which projects inwards from the casing. By this, the diameter of the support portion is increased as compared with the case in which the power input shaft is directly supported by the casing. By this structure it is possible to increase the strength of the support portion and make the casing more compact, and also the supply of lubricating oil to the biasing member is facilitated.
