PURPOSE:To make it possible to easily attach or detach a heat exchange element and to substantially set the opening to the size of the heat exchange element by causing at least one of holding parts for holding ridgelines of the heat exchange element to slide by a lever. CONSTITUTION:A holding part 3 provided on one side with a groove part 10 for holding a ridgeline of a heat exchange element 2 and an another side with a receiving plate 4 having a slot 9 is fixed to a partition plate 6 provided on the inner surface of a main body 1 of an air conditioning ventilation fan for dust by means of a screw through the slot 9 in a horizontally slidable manner. At the lower surface part of the main body 1, an opening part 7 having a size capable of pulling out the heat exchange element 2 is formed, and a lid 8 which is attachable or detachable is provided. On the lower side of the receiving plate 4, a lever 5 is fixed by means of a screw 11 fitted to the partition plate 6 to form a long shaft having a width equal to that of the receiving plate 4. In this manner, since the holding part 3 is caused to slide horizontally to conduct the fixture of the heat exchange element 2, the heat exchange element 2 can be attached or detached easily only by the rotation of the lever 5, and further the opening part 7 can be also made small. |
