2. A continuously variable transmission to be mounted on a vehicle, wherein
when an accelerator opening is decreased while the vehicle is traveling,
an upshift is performed according to the accelerator opening until a predetermined opening is reached,
when the accelerator opening is smaller than the predetermined opening, the upshift is further performed from a speed ratio when the accelerator opening is the predetermined opening so as to fix the speed ratio to be higher than the speed ratio when the accelerator opening is the predetermined opening, and
the upshift is further performed thereafter from the fixed speed ratio according to the accelerator opening.
