<P>PROBLEM TO BE SOLVED: To disassemble a valve unit without removing working oil in a transmission case. <P>SOLUTION: The working oil X is stored and a stepless transmission mechanism 20 is housed in the transmission housing chamber 19 of the transmission case 15. Further, the working oil X is stored and a valve unit 51 is housed in the valve housing chamber 50 of the transmission case 15. The valve housing chamber 50 housing the valve unit 51 is arranged above the oil level OL of the transmission housing chamber 19. Further, the valve housing chamber 50 and the transmission housing chamber 19 are in communication via a drain port 58 closed by a drain plug 59. When disassembling the valve unit 51, the drain port 58 is opened by disassembling the drain plug 59. Consequently, it is possible to move the working oil X from the valve housing chamber 50 to the transmission housing chamber 19 and it becomes possible to disassemble the valve unit 51 without removing the working oil X from the transmission case 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
