PROBLEM TO BE SOLVED: To provide an opening/closing control device for a ventilator and a cam member for use in the same, which can simplify work for mounting the cam member for tripping a limit switch and can trip the limit switch in desired timing. SOLUTION: In the opening/closing control device which is equipped with the limit switch 5 for stopping a motor and the cam member 4 for tripping the limit switch 5, the cam member 4 is mounted on a rotating shaft 3b by means of a fastening screw 16 after being unitized by fixing a fully opened cam 12, a fully closed cam 11, an opened safety cam 14 and a closed safety cam 13 to a base member 10 by means of a fixing screw 15. In the unitized cam member 4, a component can be prearranged in a relative position based on a degree of opening/closing of the ventilator. When a position of the cam 11 is adjusted so that the cam member 4 can be mounted on the rotating shaft 3b, the cams 12, 14 and 13 are automatically arranged in respective preadjusted positions. |
