Abstract
An internal combustion engine includes a variable valve control system which is operable to switch actions of an engine valve by slidably moving a rocker arm in the axial direction of a rocker-arm shaft, and which is capable of removing a restriction on the sliding movement of the rocker arm at accurate timings while employing a simplified configuration. When a trigger arm swings by a predetermined amount to the opposite side of a rocker arm, a left-hand engagement nail in engagement with an engagement groove disengages from the engagement groove, but a right-hand engagement nail still engages with an engagement groove. The left-hand engagement nail is placed on top of a left-hand deck-like portion. After that, when an action of the rocker arm makes the trigger arm further swing to the opposite side of the rocker arm, the right-hand engagement nail disengages from the engagement groove.
