摘要： A vehicle oil pump that is driven by a drive gear provided on a rotating shaft that rotates in one direction when a vehicle travels forward and rotates in the opposite direction when the vehicle travel backward includes a first driven gear that is in mesh with the drive gear and provided on a drive shaft of the vehicle oil pump via a first one-way clutch, an idler gear that is in mesh with the drive gear, and a second driven gear that is in mesh with the idler gear and provided on the drive shaft of the vehicle oil pump via a second one-way clutch. The first one-way clutch is configured to transmit rotation of the first driven gear to the drive shaft when the vehicle travels in one direction, from among forward and backward, and the second one-way clutch is configured to transmit rotation of the second driven gear to the drive shaft when the vehicle travels in the other direction, from among forward and backward.
