<P>PROBLEM TO BE SOLVED: To achieve a structure capable of maintaining a contact state between the circumferential face of a power roller 8b and each disk regardless of changes in an elastic deformation amount of each structural member by displacing the power roller 8b in an axial direction of each disk. <P>SOLUTION: A support beam 34 having a cylindrical recessed face 33 is disposed in the intermediate portion of a trunnion 9b. A partially cylindrical projection portion 38 formed on the outer face of an outer ring 37 constituting a thrust ball bearing 36 that supports the power roller 8b is engaged with the cylindrical recessed face 33 of the support beam 34. The outer ring 37 and the power roller 8b are supported so as to be swing-displaceable with respect to the trunnion 9b in axial directions of the both disks in an input side and an output side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
