Claims

[Scope of utility model registration request]

a main body 1 forming a frame through which wind can pass;
One or more opening/closing blades 3 rotatably supported by a pin 25 in the main body 1, a pinion 9 attached to the pin 25 of the opening/closing blade 3, and a pinion 9 fixedly installed in the opening/closing mechanism chamber 4 of the main body 1. the guide shaft 5, the fixed flange plate 29 fixed in the middle of the guide shaft 5, and the guide holes 33, 34 of the upper guide 31 and lower guide 32 on the guide shaft 5.
is inserted through the rack plate 6 having the rack 30 and the guide shaft 5, and is selectively provided between the upper guide 31 and the fixed collar plate 29 or between the lower guide 32 and the fixed collar plate 29. It consists of an alloy spring 7 and a bias spring 8, and a rack 30 and a pinion 9 are engaged with each other. When the shape memory alloy spring 7 extends, the rack plate 6 moves in a straight line, the pinion 9 rotates, and the opening/closing blade 3 opens. When the shape memory alloy spring 7 contracts, the rack plate 6 moves linearly in the opposite direction, and the pinion 9
An automatic opening/closing type ventilation opening using a shape memory alloy, characterized in that the opening/closing blades 3 are closed by rotating in the opposite direction.
