Abstract
A body of an oil jet is provided with: an oil supply port; a cylinder; and an oil injection port. A piston valve is accommodated in the cylinder. The piston valve forms in the cylinder a differential pressure room which is a closed compartment. In the piston valve, an orifice which makes the differential pressure room being communicated with a side of the oil supply port is formed. The piston valve is biased toward a position at which the oil injection port is closed by a spring. A first oil injection nozzle is connected to the oil injection port. A leak hole which allows oil to be leaked outside of the cylinder from the differential pressure room is open at the side surface of the cylinder. Further, a second oil injection nozzle is connected to the leak hole.
