PURPOSE: To correct the error based on different thermal expansion and wear by providing a control means to control the action of a stop cam corresponding to the running condition so that the stop cam is brought into contact with a stop face even at the closed position of a valve.
CONSTITUTION: A motor is driven through a friction clutch 14, a stop face 12 and a stop cam 11 interacted therewith are provided, the maximum valve stroke is regulated by turning the stop cam 11 by the specified angle, and the stop cam 11 is brought into contact with the stop face 12 even at the closed position of a valve 1. In addition, a control means 16 to control the action of the stop cam 11 corresponding to the running condition of an internal combustion engine is provided. In such a constitution, the valve 1 has two terminating positions, i.e., the position where a valve element is abutted on a valve seat 4, and the position where the stop face 12 is stopped. The stop cam 11 is designed so as to be brought into contact with the stop face 12 even at the closed position of the valve 1.
