Abstract:
1. A continuously variable transmission, comprising: a housing; an input shaft rotatably supported in the housing; a first speed change unit and a second speed change unit, provided within the housing and disposed facing each other symmetrically with respect to a plane normal to the axial direction of the input shaft, to continuously vary the speed of rotation of the input shaft using traction force; an output rotating body supported to be able to rotate freely about the input shaft so that the rotation of the output rotating body is synchronized with the rotation which has been varied in speed by the first speed change unit and the second speed change unit; and an output shaft rotatably supported in the housing to rotate in synchronization with the output rotating body, wherein the first speed change unit comprises the second speed change unit comprises the continuously variable transmission further comprises a loading cam mechanism that generates pressing force in the axial direction of the input shaft by a difference in rotation between the output shaft and the first output ring or the second output ring.
