機関の吸排気弁駆動装置。a valve drive cam that rotates in synchronization with engine rotation; a rocker arm that has one end linked to the valve drive cam and the other end linked to the valve stem; and a rocker arm that is disposed along the back surface of the rocker arm and has one end connected to the first shaft. The valve stem is in fulcrum contact and the other end rotates together with the second shaft and is slidably supported in the direction of the center line of the valve stem with respect to the second shaft, and the effective length is adjusted by hydraulic pressure that changes depending on the engine operating state. a lever that changes; a cylindrical groove formed in the longitudinal direction at the end of the lever on the valve stem side; and a slanted surface at one end of the lever that is fitted into the cylindrical groove and receives hydraulic pressure corresponding to the change in the effective length. An intake/exhaust valve drive device for an internal combustion engine, comprising a piston that abuts a shaft of an internal combustion engine.
