Abstract
The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is swingably supported by a single pivot, and a switching device that operates the rocker arm to switch a drive state of the valve, in which the rocker arm is configured such that at least in a predetermined drive state, a pressing force of the cam is applied disproportionately to one side of the rocker arm in a width direction with respect to a center line when the cam presses a portion of the rocker arm located away from the center line in the width direction. The variable valve mechanism further includes a swing guide that abuts against the rocker arm so that the rocker arm is guided in a swing direction so as not to be tilted in the width direction.
