At times, the first path switching means is controlled to return the hydraulic oil to the oil tank, and after the engine is started, if the oil temperature is determined to be below a predetermined temperature based on the oil temperature detected by the oil temperature detection means. A hydraulic circuit for an engine-driven vehicle, comprising: path switching control means for controlling the second path switching means so as to return hydraulic oil to the oil tank via a throttle device.
