There is provided a saddle-ridden type vehicle. An oil cooler cools engine oil to be supplied to an engine. A supercharger compresses combustion air to be supplied to the engine. A water pump pumps cooling water to the engine and the supercharger. A cooling piping flows the cooling water delivered from the water pump. A first inlet piping supplies the cooling water to the oil cooler. A second inlet piping is disposed in parallel with the first inlet piping and supplies the cooling water to the supercharger. A first outlet piping extends upward from the oil cooler and returns the cooling water to the water pump. A second outlet piping extends upward from the supercharger and returns the cooling water to the water pump. The first outlet piping and the second outlet piping converge above the oil cooler and the supercharger.
