Abstract
In a V-belt continuously variable transmission (CVT) of an ATV, a movable sheave half of a primary sheave is disposed on the outer side in the vehicle width direction with respect to a fixed sheave half, and a sheave drive mechanism for controlling the respective groove widths of the primary sheave and a secondary sheave through a driving force by an electric motor is located on the outer side in the vehicle width direction with respect to the movable sheave half of the primary sheave. A footboard of the ATV is located on the outer side of the V-belt CVT in the vehicle width direction and below a primary sheave shaft and a secondary sheave shaft. A portion of the electric motor is located above and in front of the primary sheave shaft as viewed in the sheave shaft direction. A straddle-type vehicle having the compact, yet durable V-belt continuously variable transmission achieves a speed change operation highly responsive to the vehicle running condition.
