燃エンジンの動弁装置。 A valve train for an internal combustion engine in which a rocker arm is supported on a rocker shaft supported by a rocker bracket, and a pair of valves mounted on a cylinder head are simultaneously opened and closed via a valve bridge by swinging of the rocker arm as the camshaft rotates. In the apparatus, an oil jet hole is formed in the rocker shaft or the rocker bracket, and an oil hole is formed in the rocker arm, and when the valve is not lifted together with the valve bridge, the oil jet hole is connected to the one valve. supplying oil to the contact surface between the valve shaft end and the valve bridge, and when the valve lifts together with the valve bridge, supplying oil from the oil jet hole to the sliding surface between the valve bridge and the rocker arm; A valve operating device for an internal combustion engine, characterized in that oil overflowing from the sliding surface can be supplied from the oil hole to a contact surface between the valve shaft end of the other valve and the valve bridge.
