Friction type continuously variable transmission

A friction type continuously variable transmission including an input side friction wheel drive-coupled to an input shaft, an output side friction wheel drive-coupled to an output shaft, and a friction member pressure-contacting with the input side friction wheel and the output side friction wheel and transmitting motive power with both the friction wheels, wherein a contact position of the friction member with the input side friction wheel and the output side friction wheel is changed to steplessly shift speed of rotation between the input shaft and the output shaft, the friction type continuously variable transmission comprising:

• a pressing device which is disposed between the input shaft and the input side friction wheel or between the output side friction wheel and the output shaft, and applies an axial force to pressure-contact the input side friction wheel and the output side friction wheel with the friction member, wherein
• the pressing device has a first torque cam and a second torque cam which are disposed in parallel with a transmission path of torque,
• the first torque cam passes transfer torque in a region where the transfer torque is smaller than a predetermined value so as to generate an axial force corresponding to the transfer torque, and
• the second torque cam passes transfer torque in a region where the transfer torque is larger than the predetermined value so as to generate an axial force corresponding to the transfer torque.
