Embodiment Construction
[0040] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in the following description, the "gear ratio" of a certain transmission mechanism is the value which divided the input rotation speed of the said transmission mechanism by the output rotation speed of the said transmission mechanism. In addition, the "lowest gear ratio" means the maximum gear ratio of the variator, and the "highest gear ratio" means the minimum gear ratio of the variator.
[0041] figure 1 It is a schematic configuration diagram of a vehicle equipped with a continuously variable transmission according to the present embodiment. The vehicle has an engine 1 as a power source. The output rotation of the engine 1 is transmitted to drive wheel 7. The second gear set 5 is provided with a parking mechanism 8 that locks the output shaft of the transmission 4 so that it cannot mechanically rotate when parking.
[0042] In addition, the vehicle i...
