    • PROBLEM TO BE SOLVED: To provide a lubricating device for a driving device that sufficiently supplies lubricating oil to an oil discharge hole on the downstream side of an oil supply pipe even when the amount of lubricating oil to be pressure-fed to the oil supply pipe is small.SOLUTION: A first oil discharge hole 164 located on the downstream side of an oil supply pipe 162 is provided at a position lower than a second oil discharge hole 166 located on the upstream side. Therefore, when the amount of lubricating oil to be pressure-fed to the oil supply pipe 162 from an oil pump 138 becomes small during low rotation of the oil pump 138, lubricating oil is supplied to the first oil discharge hole 164 through a part, lower than the second oil discharge hole 166, of the flow cross-section of the oil supply pipe 162. Consequently, even when the amount of lubricating oil to be pressure-fed to the oil supply pipe 162 is small, it is possible to sufficiently supply lubricating oil to the first oil discharge hole 164 on the downstream side of the oil supply pipe 162.

    • PROBLEM TO BE SOLVED: To provide a vehicular oil pump, driven by a rotation shaft in which a rotation direction when a vehicle goes forward is reversed to a rotation direction when the vehicle goes backward, capable of supplying oil whether the vehicle goes forward or backward, and having a simple structure.SOLUTION: When the vehicle goes forward, a first driven gear 168 drives a pump shaft 158 of the oil pump 120 via a first one-way clutch 166 to drive the oil pump 120. When the vehicle goes backward, a second driven gear 172 drives the pump shaft 158 of the oil pump 120 via a second one-way clutch 170 to drive the oil pump 120. By this, an oil-pressure requiring part of the vehicle can be supplied with the oil regardless of the travelling direction of the vehicle. In addition, as a special switching mechanism, etc., for switching an oil passage according to the travelling direction of the vehicle is not necessary, the device becomes simple, and manufacturing cost can be suppressed.
