機関の吸・排気弁駆動装置。 The curved back surface of the rocker arm, whose ends engage with the intake/exhaust valve drive cam and the stem ends of the intake/exhaust valves, is brought into fulcrum contact with a lever that is swingably attached to the engine body along the back surface. By controlling the lift amount of the lift control cam engaged with one end of the lever and changing the rocking position of the lever, the fulcrum position where the lever and the rocker arm come into contact is changed and the intake/exhaust valves are controlled. In an internal combustion engine intake/exhaust valve drive device in which lift characteristics are variably controlled, the lift amount of the lift control cam is controlled to be maximum, and one end of the lever swings to near the lowest position. An intake/exhaust valve drive device for an internal combustion engine, characterized in that a biasing means for biasing the lever to contact the lift control cam is provided at one end of the lever.
