Reference numeral 13 denotes a pipe connected to both ends of the ventilation fan main body, and has a diameter smaller than the outer diameter of the main body 11. Reference numeral 14 denotes a convex portion provided on the side wall of the ventilation fan main body, which consists of a pair of left and right ventilating fan main bodies 11
Is attached to a ceiling or the like (not shown). 15
Is a box in which a cushioning material and a ventilation fan main body 11, which will be described later, are installed. 16 is the ventilation fan main body 11 and the box body 1
It is a cushioning material that abuts on 5. As shown in FIG. 4, the cushioning material is a flat corrugated cardboard material, and a receiving surface 19 is provided with a fitting hole 18 into which the pipe 13 is fitted through a ruled line 17, and both sides of this receiving surface. Of the side surfaces 20, 21, a contact surface 22 continuous with one of the side surfaces 20, and a holding surface 23 continuous with the contact surface. 24
Is a holding piece, and has a recess 25 formed by notching the side end of the holding surface 23 in an inverted trapezoidal shape, and the inlet is wide so that the projection 14 can be easily fitted into this recess. The fitting portion has the small shape described above. Reference numeral 26 is a stitching wire for fixing the cushioning material 16 in a sleeve shape.

In the packaging apparatus constructed as described above, the shape shown in FIG. 4 is stamped out from a flat corrugated board material by a press or the like, bent into a sleeve shape through the ruled line 17, and the end of the side surface 21 is cut. The part is brought into contact with the contact surface 22, and the holding surface 23 and the side surface 21 are overlapped and fixed by the stitching wire 26. As a result, the cushioning material 16 is formed, and the holding piece 24 is provided to project perpendicularly to the receiving surface 19 having the fitting hole 18. Next, by fitting the pipes 13 at both ends of the ventilation fan main body 11 into the fitting holes 18 of the cushioning material 16 and the convex portions 14 into the recesses 25, the ventilation fan main body 11 is fixed to the cushioning material 16 also as a rotation stop. To be done. Then, after the cushioning material 16 is attached to both ends of the pair of ventilation fan main bodies 11 as shown in FIG.
The packaging device is formed by enclosing the packaging device in 5.

Embodiment 2. Further, as shown in FIGS. 5 and 6, the second holding piece 30 is integrally formed by cutting and raising the receiving surface 19.
To form a pair of left and right holding pieces 2 on the receiving surface 19.
4 and 30 are provided and both the convex portions 14 are fitted together, so that the holding function can be more reliably performed.

Embodiment 3. Further, as shown in FIGS. 7 and 8, by providing a pair of left and right holding pieces 24 by cutting and raising from both ends of the receiving surface 19, the same effect as that of the first embodiment can be obtained, and the cushioning material 16 Less material is taken and the manufacturing cost can be reduced.

Embodiment 4. Further, as shown in FIGS. 9 and 10, by cutting and raising the cushioning piece 40 in parallel with the fitting hole 18 from the side surface 20 of the cushioning material 16, the cushioning function for the ventilation fan main body 11 has a receiving surface 19, A cushioning function is added to the contact surface 22 and the holding piece 24, and the holding function of the ventilation fan main body 11 is further improved.

[0014]

As described above, according to the present invention, a ventilation fan main body having a cylindrical side wall provided with a convex portion, a sleeve-shaped cushioning material for holding both ends of the ventilation fan main body, the cushioning material and the ventilation fan. A box body in which the main body is installed, the cushioning member is provided with a fitting hole into which the ventilating fan body is fitted, and a recess having an inverted trapezoidal shape into which the convex portion is fitted, By providing the holding piece protruding vertically to the dowel, it becomes easy to fit and install the cushioning material to the ventilation fan main body, and further the cushioning effect including the rotation stop of the ventilation fan main body is improved.

Further, since a cushioning piece which abuts the convex portion of the ventilation fan main body is provided in parallel with the fitting hole from the side wall of the cushioning material,
