A power transmitting apparatus, comprising: a power transmission route that transmits output of at least one of a mechanical power source generating a driving force by using mechanical energy as power and an electric power source generating a driving force by using the mechanical energy obtained by converting electric energy as power to a drive wheel (WL, WR) side; a power transmission mode adjusting device configured to operate based on pressure of a fed fluid to adjust a mode of power transmission from the mechanical power source or/and the electric power source on the power transmission route; a first driving pump configured to feed the fluid to the power transmission mode adjusting device by being driven in accordance with rotation of a rotation axis of the electric power source; and a second driving pump configured to feed the fluid to the power transmission mode adjusting device by being driven in accordance with electric power, wherein a first engagement unit and a second engagement unit of the power transmission mode adjusting device can be caused to engage rapidly or slowly, depending on a fluid pressure provided by the first or second driving pump (51, 55), by selecting one of the first driving pump and the second driving pump as a source of the fluid to the power transmission mode adjusting device, wherein the second driving pump is configured to provide a larger discharge amount of the fluid per unit time than a maximum discharge amount of the fluid per unit time provided by the first driving pump, and when a drive request of the power transmission mode adjusting device is present and a rotation speed of the electric power source is lower than a predetermined rotation speed, the first engagement unit and the second engagement unit are caused to engage rapidly by feeding the fluid from the second driving pump. a power transmission route that transmits output of at least one of a mechanical power source generating a driving force by using mechanical energy as power and an electric power source generating a driving force by using the mechanical energy obtained by converting electric energy as power to a drive wheel (WL, WR) side; a power transmission mode adjusting device configured to operate based on pressure of a fed fluid to adjust a mode of power transmission from the mechanical power source or/and the electric power source on the power transmission route; a first driving pump configured to feed the fluid to the power transmission mode adjusting device by being driven in accordance with rotation of a rotation axis of the electric power source; and a second driving pump configured to feed the fluid to the power transmission mode adjusting device by being driven in accordance with electric power, wherein a first engagement unit and a second engagement unit of the power transmission mode adjusting device can be caused to engage rapidly or slowly, depending on a fluid pressure provided by the first or second driving pump (51, 55), by selecting one of the first driving pump and the second driving pump as a source of the fluid to the power transmission mode adjusting device, wherein the second driving pump is configured to provide a larger discharge amount of the fluid per unit time than a maximum discharge amount of the fluid per unit time provided by the first driving pump, and when a drive request of the power transmission mode adjusting device is present and a rotation speed of the electric power source is lower than a predetermined rotation speed, the first engagement unit and the second engagement unit are caused to engage rapidly by feeding the fluid from the second driving pump.
