PURPOSE:To promote the accuracy of combination and simplify disassembly and assembly by a mechanism wherein arms are mounted which are integrally formed with the seal surfaces of heat exchanging elements while the arms are positioned at a boundary portion between a feed current and an exhaust current. CONSTITUTION:Elements 13 are arranged at the indoor side of a fan, and an element shaft 20 is supported to a support portion 21, which is installed to a frame 14 and is directed only in the one direction. The support portion 21 is integrally made up with arm portions 19. Thus, the elements 13 can simply be mounted and demounted only by extracting them to the indoor side while the high effect of ventilation can be obtained by periodically cleaning the elements 13. The quantity of leaking air is lowered because the arm portions 19 make clearances among the end surfaces of the elements 13 and the arm portions small. Since the support portion 21 is integrally connected to the elements 13 through the element shaft 20, the support portion can easily be returned to the original position even when the elements 13 are mounted and demounted. Thus, the quantity of leaking air, is decreased, and the ventilating device is positively disassembled and assembled. |
