<P>PROBLEM TO BE SOLVED: To provide a charge structure for supplying oil discharged from a charge pump to an oil filter and supplying oil purified by an oil filter to a charge oil path without using an external pipe. <P>SOLUTION: A hydrostatic continuously variable transmission 5 having a port block 21 connected to a shift casing 2b is connected to the end face of a transmission case 3 so that the port block 21 is located on the side of the transmission case. The charge pump CP is mounted at the port block 21 on the side of the transmission case. Oil discharged from the charge pump CP is guided and supplied to an oil filter 28 mounted on the outer face of the transmission case 3 via the port block 21, the transmission casing 2b, and internal oil paths, e, f, g formed in the wall of the transmission case 3. Oil passing through the oil filter 28 is guided to the charge oil path of the port block 21 via the transmission case 3 and the internal oil paths formed in the wall of the transmission casing 2b. <P>COPYRIGHT: (C)2007,JPO&INPIT |
