<P>PROBLEM TO BE SOLVED: To provide a ventilation controller, which can switch the state of air inflow prevention into a building, regardless of outside air temperature, on the basis of an automatic switching mechanism for prevention of an inflow of air into a building suitable for outside air temperature and into a dischargeable state, according to a change in outside air temperature. <P>SOLUTION: The ventilation controller has a shutter part 20, which has a shutter plate 24 rotating around a rotating shaft 22, a first energizing member 32 of a thermosensitive shape memory alloy, a second energizing member 34 of a usual spring material, a slide body 37, which slides and shifts, using, as its driving source, a difference by a change in outside air temperature between the energizing force by a first energizing member 32 and the energizing force by a second energizing member 34, a link part 35, which converts the action of a slide body 37 into the rotational motion of the rotating shaft 22, and a lever 40, one end of which is fixed to the link part 35 and the other end of which is guided by the guide part 14A of the body 10 so that it may enter or project from the body 10 in cooperation with the action of the link part 35. <P>COPYRIGHT: (C)2012,JPO&INPIT |
