A rotating control mechanism of the shutter louver is disposed at a louver and includes an anchor, a bush, and a screw. The anchor has an opening end and a closed end, so as to form a first separating portion and a second separating portion respectively corresponding to a major axis in a radial direction of the louver. The bush has a cylinder portion neighboring to the frame and embedded in the counterbored hole of the frame, and an annular flange attached to the frame and the louver and/or the opening end of the anchor with both sides respectively. The screw passes through the counterbored hole and the bush in sequence to lock the anchor, such that the anchor moves towards the major axis direction of the louver and stops at a screw on an inner surface of the axial hole, so as to prevent the louver from cracking.
