A hydraulic circuit includes a first oil path, a second oil path, a hydraulic control circuit, a third oil path, a check valve, and a relief valve. The first oil path links to a discharge port of a first oil pump. The second oil path links to a discharge port of a second oil pump. In the hydraulic control circuit, a first regulator valve is disposed downstream of a confluence point of the first oil path and the second oil path. The third oil path connects a suction port of the first oil pump and a strainer. The check valve is provided in the third oil path and restricts a movement of oil toward the strainer side. The relief valve is provided in the third oil path and discharges oil in the third oil path to an outside when a pressure in the third oil path exceeds a reference pressure.
