Abstract
According to the present invention, there is provided a V-belt type contiuously variable transmission wherein the lowest forward speed ratio is accomplished by drivingly connecting a forward low gear to a transmission input shaft when a forward low clutch is engaged, and wherein a shift to the adjacent next low forward speed ratio higher than the lowest forward speed ratio is made when a forward high clutch is engaged with the forward low clutch kept engaged, therby to allow continuous variation of speed ratio, and wherein a reverse speed ratio is accomplished by engaging a reverse gear to the transmission input shaft when a reverse clutch is engaged. There is provided a gear train meshing with the reverse gear and arranged in parallel to the one-way clutch. Thus, a power delivery path during the reverse speed ratio is established through the reverse gear and the gear train arranged in parallel to the one-way clutch.
