<p><P>PROBLEM TO BE SOLVED: To provide a compact and low-cost driving device for a hybrid vehicle, which maintains lubricating-oil supplied to a clutch device in a suitable temperature. <P>SOLUTION: An oil passage 52 for communicating an oil reservoir part 21 in a case 11, a pump 7, a valve 26 and the hydraulic chamber PC of the clutch device 3 and supplying and delivering the lubricating oil D to and from the hydraulic chamber is formed in a wall of the case, and excessive cooling of the lubricating oil in the oil passage caused by traveling air generated in traveling of the vehicle can be prevented. Then, the viscosity of the lubricating oil can be suitably maintained, and performance of the electric pump can be fully exhibited, and the lubricating oil can be smoothly supplied. Further, a valve element storage part 11e for storing a valve element 26a of the valve is formed in the wall of the case, dispensing with a valve body, with miniaturization and cost reduction in the driving device for the hybrid vehicle. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
