装置。 A plurality of rocker arms are supported on the rocker shaft, which is fixedly supported on the cylinder head, to drive the engine valves to open and close, and these rocker arms can be connected and disconnected to each other according to the operating state of the engine according to hydraulic pressure. In a valve train for an internal combustion engine, a hydraulic coupling switching mechanism is provided, and an oil supply passage leading to the hydraulic coupling switching mechanism is provided in the shaft. A supply passage is opened in the cylinder head, and a spool valve body with one end facing the hydraulic pressure chamber and biased by a spring slides into the housing in order to switch between communication and isolation between the hydraulic supply passage and the oil fill port. A switching valve that can be reliably fitted is attached to the cylinder head, and a leak jet communicating with the hydraulic pressure chamber and opening toward the top of the cylinder head is bored in the housing of the switching valve. Valve gear for internal combustion engines.
