<P>PROBLEM TO BE SOLVED: To provide a driving system capable of properly securing a traction coefficient of a continuously variable transmission by suppressing delusion of oil used in the continuously variable transmission. <P>SOLUTION: The driving system includes: a communication part 13 through which a first storage chamber 11 storing the continuously variable transmission and a second storage chamber 12 storing a gear mechanism communicate with each other; and a shaft 10 inserted in the communication part 13, for connecting the continuously variable transmission and the gear mechanism. The driving system also includes a single oil seal 15 disposed on the outer circumference of the shaft 10, for sealing the communication part 13, wherein the oil seal 15 is provided with a pump structure for pushing an oil that flows from the second storage chamber 12 into the first storage chamber 11, back to the second storage chamber 12 when the shaft 10 is in positive rotation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
