<p><P>PROBLEM TO BE SOLVED: To provide a vehicle driving device capable of miniaturizing a driving device, and capable of reducing weight, by miniaturizing an oil pump, in the vehicle driving device for transmitting power from a power source to the output side via a planetary gear device. <P>SOLUTION: A one-way clutch OWC is arranged on the inner peripheral side of a ring gear R1, and an oil pump 30 is connected to the one-way clutch OWC via an oil pump shaft 32 so that the power can be transmitted, and thus, the oil pump 32 and the one-way clutch OWC are arranged in a position different in the axial direction, and an inner diameter of the oil pump 30 is set smaller than an outer diameter of the one-way clutch OWC. With such a constitution, the inner diameter of the oil pump 30 can be reduced more than the outer diameter of the one-way clutch OWC. With such the setting, the oil pump 30 can be miniaturized in the radial direction. The oil pump 30 can also be shortened in the axial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
