ABSTRACT:
A continuously variable transmission reduces slips between a primary sheave and a V-belt when decelerating. A target value setting section sets a control target value for control by a control device. In the target value setting section, a normal mode, a kick down mode set to be in a Low gear range lower than in the normal mode, and a restriction value given in a throttle fully closed state are provided. The control device controls the continuously variable transmission based upon the kick down mode provided in the target value setting section, in response to an operation of a kick down operator. The control device controls a gear ratio of the continuously variable transmission not to vary to a Low gear range lower than the restriction value provided in the target value setting section.
