Abstract:
A first rod is rotatably connected to a first drive lever shaft and a first valve lever shaft. A second rod is rotatably connected to a second drive lever shaft and a second valve lever shaft. A first predetermined shape portion is formed at a location, which is spaced from an axis of an output shaft by a predetermined distance. A second predetermined shape portion is formed in a second drive lever and is contactable with the first predetermined shape portion. A spring is placed between the actuator and the second drive lever and urges the second drive lever in a predetermined direction, which coincides with a closing direction of a second valve and an approaching direction of the second predetermined shape portion toward the first predetermined shape portion.
