Abstract:
A variable valve mechanism comprising:a first intervening member that rotates a small angle rotation about an axis of a support shaft by being pressed by a rotating cam; a second intervening member that lifts a valve by making a small angle rotation about an axis of said support shaft together with said first intervening member thus pressing a cam corresponding part of a rocker arm; a control shaft provided concentrically with said support shaft; a slider that moves with said control shaft; a slanted part formed diagonally relative to said slider's movement direction, contacting with said slider; and a relative rotation angle control device, wherein said relative rotation angle control device varies the relative rotation angle of said first intervening member and said second intervening member by pressing said slanted part in a direction substantially perpendicular to said slider's movement direction by moving said slider together with said control shaft, thus varying the valve's lift and operating angle continuously.
