Disclosed is a friction wheel-type continuously variable transmission having a pressing device which can obtain the required axial force even with an extremely low torque with the first roll or the like when there is no load, such as when being towed. The pressing device (12) has: a first stage, which is based on the precompression of a spring (13); a second stage, which is based on a first torque cam (15), whereby torque is transmitted entirely through said first torque cam; and a third stage, which is based on a second torque cam (20), whereby torque is transmitted entirely through said second torque cam. The first stage has a constant axial force, the second stage is comprised of a relatively large slope (alpha), and the third stage is comprised of a small slope (beta).
