PURPOSE:To decrease transmission torque and reduce the size of a continuously variable transmission gear by coupling a split-coupling formed by combination of a Lavinoir planetary gear set with a fluid coupling to the output side of a V-belt continuously variable transmission gear. CONSTITUTION:A split-coupling 4 formed by combination of a Lavinoir planetary gear set 5 comprising a short planetary gear 54 engaged with a small sun gear 52 and a long planetary gear 55 engaged with a large sun gear 53 with a fluid coupling which is a power transmission device is coupled to the output side of a V-belt continuously variable transmission gear 2. In this arrangement, as the torque transmitted through the fluid coupling 6 is a part of the total transmission torque, the outside dimension of the fluid coupling can be reduced. |
