A hydraulic circuit for a vehicle driving device includes an oil pump, a clutch oil passage, a cooling oil passage, a pressure regulating valve, and a shift valve. The cooling oil passage guides oil to a cooled portion of a vehicle. Supply of oil to the clutch oil passage and the cooling oil passage is switched by switching of the pressure regulating valve and the shift valve. The cooling oil passage includes: a shaft center cooling oil passage which supplies cooling oil to a shaft center of a rotation shaft of an electric motor mounted on the vehicle; and a cooling oil passage shift valve which switches presence/absence of supply of oil to the shaft center cooling oil passage.
