PROBLEM TO BE SOLVED: To provide a lubricating device for a driving force transmitting device of a hybrid vehicle capable of excellently lubricating the inside of a two-way clutch. SOLUTION: A hybrid vehicle comprises front wheels driven by an engine and rear wheels driven by an electric motor through a reduction gear mechanism, and a two-way clutch is assembled between a large-diameter gear 27 of a reduction gear A2 which is positioned at the upstream side of the final reduction gear of the reduction gear mechanism, and a second shaft 22 which is arranged to pass through freely to relatively rotate so as to transmit rotation torque from the rear wheels to the electric motor when travelling by the drive of the engine. The second shaft 60 has an axial directional hole 60 extended in the axial direction from the shaft end surface and a radial directional hole 61 extended in the radial direction from a cylindrical outer surface 47 forming a clutch space between the cylindrical inner surface 42 of the large-diameter gear and communicating with the axial directional hole. An oil supply nozzle 62 for supplying lubricating oil is inserted into the axial directional hole, and the lubricating oil fed from the oil supply nozzle into the axial directional hole 60 is made to flow from the radial directional hole into the clutch space for lubrication.
