<P>PROBLEM TO BE SOLVED: To provide a compact-sized and light-weighted variable speed transmission device, achieving switching of a clutch mechanism in good timing, and also supplying lubricant to the respective planetary transmission mechanisms. <P>SOLUTION: This transmission device includes: a planetary transmission part P for synthesizing the output of a continuously variable speed part 20 to which the engine driving force is input and the engine driving force not subjected to variable speed action of the continuously variable speed part by a plurality of planetary transmission mechanisms 40, 50; and a variable speed transmission part Z for classifying the synthesized driving force into the speed ranges of two or more stages and transmitting the same to an output rotor by switching between a plurality of clutch mechanisms 60, 70, 110, 120 for transmitting the synthesized driving force from the planetary transmission parts to the output rotor 90 and a brake mechanism 100 acting on a speed reducing planetary transmission mechanism 80 for reducing the speed of the synthesized driving force. A support shaft 97 supporting the plurality of planetary transmission mechanisms and the speed reducing planetary transmission mechanism 80 is provided with an oil supply passage bored for supplying lubricant to the plurality of planetary transmission mechanisms 40, 50 and the speed reducing planetary transmission mechanism. <P>COPYRIGHT: (C)2009,JPO&INPIT |
