PROBLEM TO BE SOLVED: To transmit a greater capacity of torque while reducing local stresses on trunnions even when great axial force is applied from a thrust mechanism. SOLUTION: This toroidal continuously variable transmission comprises an input shaft, an input disk and an output disk supported mutually concentrically on the input shaft in a mutually independently rotatable manner, and a tilting shaft 7 existing at a position perpendicular to the directions of the center axes of the input disk and the output disk. It also has at least a pair of trunnions 21 tilting around the tiling shaft 7, a plurality of power rollers rotatably supported by the trunnions and held between the traction faces of the input disk and the output disk, and a safety cable bridged on the trunnions 21 for synchronizing the tilting angles of the trunnions. Cable grooves 27 in which the safety cable is mounted are provided only at both ends of each trunnion 21 on the outer peripheral face at the end of the tilting shaft. COPYRIGHT: (C)2005,JPO&NCIPI
