機構。[Claims for Utility Model Registration] (1) A frame 1 having one or more holes 2a, 2b, etc., which is rotatably pivoted to the frame 1, and which opens the holes by rotation. A rotary shutter plate 3 formed with openings 5a, 5b for gradually controlling the opening and closing of the shutter plates 2a, 2b... A concentric arc-shaped relief groove 6 bored in the shutter plate 3, an engaging pin 7 bored on the shutter plate surface outside the center of the relief groove 6, and a base plate through the relief groove 6 of the shutter plate 3. An operating shaft 8 is rotatably supported, and an elongated slit 10 whose base is rotatably fixed to the operating shaft 8 and formed in the axial direction is slidably engaged with the engaging pin 7 of the shutter plate 3. A valve opening/closing mechanism comprising: a linking arm 11; (2) A locking part 15 is provided at the tip of the slit 10 of the linking arm 11, so that the engaging pin 7 of the shutter plate 3 is connected to the slit 1 when the shutter plate 3 is in the fully closed position and the fully open position.
1. The valve opening/closing mechanism according to claim 1, wherein the valve opening/closing mechanism is configured to abut against the tip engaging portion 15 of No. 0.
