Abstract
A valve control apparatus is provided with a valve, a shaft supporting the valve, an end-gear of an actuator driving the valve. The shaft is press-inserted into the end-gear. A stopper disposed on the shaft regulates a valve operation range. The end-gear can engage with the middle gear of the reduction-gears mechanism even in out of the gear-operation-angle range. When a rotation angle sensor detects a rotation angle of the end-gear in out of the gear-operation-angle range, it is determined that a malfunction occurs in a rotation-force-transmitting path.
