PURPOSE:To make it possible to remove the main body of the ventilating fan without breaking a cooling plate, by forming a unitary body by a suspending metal and a duct joint, and making it possible to slide and mount a part of the duct joint freely by slide guides arranged in a part of a main body case. CONSTITUTION:The main body 4 of the ventilating fan is fixed to suspending bolts 2 which are embedded in a slab 1 by nuts 3 by way of the suspending metal 10. A grill 9 of the main body 4 is bonded to the ceiling plate 16. At this time, the suspending metal 10 is formed by providing the duct joint 11, a slide plate 7 having a thread part 8, and a supporting plate 14 so as to form a unitary body. The slide guides 5 and 6 are formed on the side surfaces of the main body corresponding to the slide plate 7 in the main body 4 of the ventilating fan. In the attachment of the main body 4 of the ventilating fan, the slide plate 7 is engaged between the slide guides 5 and 6, and the main body 4 and the suspending metal 10 are assembled unitarily. Thereafter a wing bolt 12 is screwed into the thread part 8 and tightened, and both 4 and 10 are assembled into a unitary body. |
