Abstract
A toroidal-type continuously variable transmission includes an input shaft, an input disk and an output disk, plural power rollers, a power roller bearing, an oil passage, and a mesh filter. The input and output disks are supported mutually concentrically with the input shaft and mutually independently rotatably. The plural power rollers are sandwiched between the input disk and the output disks. The power roller bearing rotatably supports the power rollers. The oil passage for leading lubricating oil to the power roller bearing. The mesh filter is provided in the oil passage. Accordingly, the toroidal-type continuously variable transmission can prevent an occurrence of biting-in of foreign substances at a power roller bearing, to thereby increase the life of the power roller bearing.
