ABSTRACT:
A continuously variable transmission apparatus is constructed by a combination of a toroidal-type continuously variable transmission unit (11a) and a planetary-gear-type transmission unit (12c). The planetary-gear-type transmission unit (12c) includes a carrier (24d), a plurality of first planetary gears (44), a hollow rotary shaft (33), a first sun gear (45), a plurality of second planetary gears (46), a second sun gear (47) and a ring gear (48). The first and second planetary gears (44, 46) are meshed with the single ring gear (48) while said first and second planetary gears (44, 46) are supported on said carrier (24d) independently of each other.
