Claim Text:
1. A continuously variable transmission comprising: a driving shaft and a driven shaft; a casing that supports the driving shaft and the driven shaft so as to be substantially parallel to each other and be rotatable around respective axis lines while allowing the driving shaft to be operatively connected to a driving power source; a belt type variable speed-change mechanism that includes a driving-side pulley supported by the driving shaft in a non-rotatable manner relative to the driving shaft, and a driven-side pulley supported by the driven shaft in a non-rotatable manner relative to the driven shaft, the belt type variable speed-change mechanism being accommodated in the casing and transmitting a rotational power from the driving shaft to the driven shaft in a state capable of continuously varying a rotational speed of the rotational power to be transmitted to the driven shaft; a constant-speed power-transmitting mechanism that includes a constant-speed driven-side rotational body supported by the driven shaft in a rotatable manner relative to the driven shaft, the constant-speed power-transmitting mechanism being accommodated in the casing and transmitting the rotational power at a constant-speed from the driving shaft to the constant-speed driven-side rotational body; and a planetary gear mechanism that is supported by the driven shaft in the casing and that includes a sun gear supported by the driven shaft in a non-rotatable manner relative to the driven shaft so as to receive a variable-speed rotational power through the driven shaft, a carrier supported by the constant-speed driven-side rotational body so as to receive a constant-speed rotational power through the constant-speed driven-side rotational body and an internal gear outputting a rotational power made by combining the rotational power of the sun gear and the carrier, wherein the carrier supports a planetary gear in a rotatable manner around an axis line, and wherein the planetary gear revolves around the sun gear.
