Abstract
In a continuously variable transmission (“CVT”) using a toroidal-race continuously variable ratio device and a planetary gear mechanism, the rotation of the input shaft (12) is directly transmitted to the carrier C of the planetary gear mechanism (61), and rotation resulting from gearing and reversal by the variator (5) is transmitted to the sun gear (S1). When the low clutch L is engaged, the rotation of the ring gear (R3) is transmitted via the reversing gear mechanism (71) to the output shaft (13), and when the high clutch H is engaged, the rotation of the sun gear (S2) is transmitted to the output shaft (13).
