Abstract
The present invention provides a variable valve mechanism of an internal combustion engine which includes a rotary cam, an output arm, an input member, and a switching device that switches between a coupled state and a non-coupled state. The variable valve mechanism changes a drive state of the valve by the switching operation. The input member includes an annular input roller that contacts the rotary cam, and a swing pin that is inserted into the input roller so as to rotatably support the input roller and that swings relative to the output arm when in the non-coupled state. A center of the relative swinging movement is located at a position different from a rotation center of the input roller which is located inward of the input roller.
