<p>A continuously variable transmission, comprising a carrier (30) rotating together with an input shaft (20), a sun gear (50) rotating together with an output shaft (40), a plurality of planetary gears (60) supported on the carrier (30) in the meshed state with the sun gear (50) and capable of revolving around the sun gear according to the rotation of the input shaft, and a ring gear (70) meshed with the plurality of planetary gears (60). A rotor type continuously variable mechanism is formed of the contact surface (72) of the ring gear (70) in contact with the first conical surface (91) of a traction rotor (90), the contact surface (101) of a traction ring (100), and the cylindrical contact surface (82) of a movable disk (80) in contact with the second conical surface (92) of the traction rotor (90). The movable disk is moved in the axial L direction to continuously vary the relative rotational speed of the carrier to the ring gear. Thus, the continuously variable transmission reduced in cost and size and having a wide shift range can be provided.</p> |
