A variable valve system of an internal combustion engine varies an operation manner of an engine valve by controlling an angular position of a control shaft. The system comprises a stopper mechanism that determines an angular range in which the control shaft is permitted to rotate about its axis; an actuating mechanism that actuates the control shaft to rotate about its axis; and a position matching device that is practically assembly only when the actuating mechanism is being assembled. The position matching device, when assembled, restricts operation of the actuating mechanism in such a manner as to match a maximally operated position of the actuating mechanism with a maximally operated angular position of the control shaft.
