Further, when the position is detected by the Hall element 46, since the stepping motor 12 is configured to rotate in the same direction, the hysteresis of the Hall element 46 (the deviation of the detection angle due to the rotation direction) is always constant. Therefore, it is possible to detect an exactly determined position.
Also, as shown in FIG.
Since the mounting angle is shifted by a fixed value A, there is no need to consider a positional shift due to hysteresis.
