Abstract
In an EGR valve, an actuator includes a coil, a rotor body to be driven to rotate when the coil is energized with electric current, and a converting mechanism to convert rotational movement of the rotor body into stroke movement of the rod to bring a valve into or out of contact with a seat. The rod includes a stopper that will contact with a protrusion of the rotor body when the valve is placed in a full closed state. An end face of the stopper and an end face of the protrusion are slanted with respect to a stroke direction of stroke movement of the rod.
