とになる。FIG. 4 shows the relationship between the head 7a of the screw 7 and the hole 1c in the state shown in FIG.
In a state where the screw 7 is housed in the hole 1c,
The axial center of the screw 7 is lower than the center of the hole 1c in the figure,
That is, the length from the screw center axis to one edge of the action portion is longer than the length from the screw center axis to the inner peripheral surface of the hole 1c closest to the vertical plate portion 2a. FIG.
In the state of (a), since the operating portion (long side direction) of the head portion 7a faces the direction parallel to the surface of the vertical plate portion 2a of the duct connecting plate 2, the operating portion of the head portion 7a corresponds to the hole 1c. It is not pressed against the inner surface. Next, the screw 7 is turned in the F direction as shown in FIG. Then, due to the acting portion of the head portion 7a, the vertical plate portion 2a is formed on the inner peripheral surface of the hole 1c.
The pressing force is applied in the direction (position S in the figure) in which is located. Further, as shown in FIG. 5C, by further turning the screw 7, as shown in FIG. 5, the acting portion (long side direction) is perpendicular to the surface of the vertical plate portion 2a. 4C, the ventilation fan main body 1 moves by a distance A in the direction in which the vertical plate portion 2a is located (S direction) in FIG. 4C. By moving the ventilation fan main body 1 in the S direction in this manner, sufficient force for pressing the packing 8 is applied.
Further, since the ventilation fan main body 1 moves in the S direction as a whole, the side surface of the ventilation fan main body 1 can press the entire surface of the packing 8 substantially evenly, and the vertical plate portion 2a and the side surface of the ventilation fan main body 1 This will ensure that the seal between and is maintained.

少ないという効果も併せて奏する。As described above, according to the ventilation fan and the method for mounting the ventilation fan of the present invention, the ventilation fan main body is pushed in the direction in which the vertical plate portion of the duct mounting plate is positioned,
Since the side surface of the ventilating fan body is in close contact with the vertical plate portion, the duct connecting plate and the ventilating fan body are reliably sealed. Further, since the close contact state can be formed only by performing the operation of turning the screw, there is an effect that the burden on the operator is small.
