Abstract
Plural cooling passages extending radially are formed from the inner circumference to the outer circumference and within an output disk common to two toroidal transmission units. Lubricating oil which has reached an annular space between the output disk and the main shaft via holes from an oil passage in the main shaft, flows into the cooling passages inside the output disk, and the output disk is thereby cooled from inside.
