To provide a combustion gas amount control device capable of sufficiently simplifying a control configuration and moving a movable plate in a superior accurate manner.
A motor control part U for controlling an action of a stepping motor 18 for operating to move a movable plate is constituted such that the number of pulses applied to the stepping motor 18 is defined under a state in which the number of pulses applied is managed in reference to a condition that an output shaft is rotated to a set reference rotary phase and under a state in which a pre-set number of clearance correction pulses is added in correspondence with a cooperative relation of a cooperating mechanism for cooperatively relating between the output shaft and the movable plate when the rotating direction of the stepping motor 18 is changed, and further the motor control part U is constituted such that the stepping motor 18 is driven in such a way that the output shaft is rotated under the set reference rotary phase on the basis of the detected information of rotary phase detecting means PM for detecting the rotary phase of the output shaft when the stepping motor 18 is operated to cause the output shaft to show the set reference rotary phase.
