<p><P>PROBLEM TO BE SOLVED: To provide a toroidal type continuously variable transmission which can support sliding movement of a power roller in an axial direction of a disk and in which a support structure thereof is difficult to be effected with an influence of an elastic deformation of a trunnion without complicating working steps. <P>SOLUTION: An oval hole 102 extending in the direction O" perpendicular to a second axis O' is formed on a central portion in the second axis O' direction of a main body portion 16 of the trunnion 15, a bearing 100 supporting an outer ring 28 movably in the direction O" perpendicular to the second axis O', is mounted between the main body portion 16 of the trunnion 15 and the outer ring 28, the outer ring 28 has a first shaft portion 106 rotatably supporting a power roller, and a second shaft portion 104 arranged concentrically with the first shaft portion 106 and movably supported by the oval hole 102 of the trunnion 15 along the direction O" perpendicular to the second axis O', and tangential forces generated between the power roller, and input and output side disks are supported between the second shaft portion 104 and the trunnion 15. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
