Abstract (en)
The present invention provides a variable valve mechanism that includes a drive cam for supplying a driving force, a link mechanism that opens and closes a valve by transmitting the driving force to the valve and has a plurality of rocking levers connected in sequence by respective joints so as to be relatively rotatable, and a variable mechanism that changes an opening and closing amount of the valve by displacing the link mechanism. One of the rocking levers of the link mechanism is provided with a length adjustment mechanism for adjusting a length of the one rocking lever in which the length adjustment mechanism is provided, and the opening and closing amount of the valve can be adjusted by adjusting the length using the length adjustment mechanism.
