<p><P>PROBLEM TO BE SOLVED: To provide a toroidal type non-stage transmission which can improve the durability of a thrust rolling bearing by suppressing the tilt of power rollers composing the thrust roll bearing. <P>SOLUTION: In the toroidal type non-stage transmission, a first shaft portion 123a is projectingly arranged on the outside side face of an outer race 128 at a position shifted from its central portion, and the first shaft portion 123a is rotatably supported by a trunnion. In addition, a second shaft portion 123b is projectingly arranged on the large end face 111c of a power roller 111 so as to be concentric with the power roller 111, and the second shaft portion 123b is rotatably supported at the central portion of the outer race 128 by means of a bearing 141a arranged on the outer periphery of the second shaft portion 123b. In this case, the second shaft portion 123b is formed such that the position P1 of its base end is positioned on the side of the small end face 111d than the position of the large end face 111c. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
