<p>PROBLEM TO BE SOLVED: To provide an oil pump device having an internal combustion engine drive source and a motor, capable of suppressing increase of the size in the radial direction.SOLUTION: An oil pump device 100 includes an internal combustion engine drive source 3 transferring driving force of an internal combustion engine to an inner rotor 11 of an oil pump 1 having the inner rotor 11 and an outer rotor 12, a motor 2 rotationally driving the inner rotor 11 of the oil pump 1, and drive source switch means 4 switching a drive source of the inner rotor 11 of the oil pump 1 to at least one of the motor 2 and the internal combustion engine drive source 3. The drive source switch means 4 includes OSV 41 which turns on and off hydraulic pressure from the oil pump 1. The oil pump device 100 is configured such that the ON/OFF control of the OSV 41 performs the switch to at least one of the motor 2 or the internal combustion engine drive source 3 to drive the inner rotor 11.</p> |
