Instead of planet gear control driving using a planetary gear structure, the continuously variable transmission mechanism performs ring gear driving and control using an input rotational force. Push arms (1), which are provided with a power roller (9) and a drive roller (8), are supported on a support frame (4), which supports planet gears (11) that mesh with a sun gear (12). Cam arms (2), which are supported by a ring-shaped outer circumferential support frame (5) and have upper and lower cam peaks, an outer cam (3) and a control gear (6) are disposed on the periphery of: drive arms (7), which are supported by a central shaft (13) and are provided with a pawl; a ring gear (10) in which ratchets have been cut; and the planetary gear structure. The drive arms (7) are driven in a reciprocating manner by pushing the cam arms (2) using the control gear (6) and driving the push arms (1) in a reciprocating manner. Ring gear driving and control using an input rotational force is performed in a form that adds an input direction rotational force on the output side sun gear (12) by applying via a one-way mechanism a drive force in the direction opposite to the input direction on the ring gear (10), which is rotating at the same time and in the same direction as the input direction, and applying an autorotational driving force in the direction opposite to the input direction on the planet gears (11). |
