The pipe body 2 in which the distal end of the pressing member 5 is protruded into the pipe body 2 is inserted into the ventilation hole Z.
And the flange 3 is brought into contact with the indoor surface member X. Since the tip of the screw 8 is screwed into a predetermined position of the pressing member 5, when the screw 8 as a pulling member inserted or screwed into the predetermined position of the flange 3 is screwed, the pressing member 5
Rotates, the tip of the pressing member 5 rotates from the cutout hole 4 of the pipe body 2 to the outer periphery of the pipe body 2, and the tip of the pressing member 5 is positioned radially from the axis of the pipe body 2. When it comes, the rotation stop member 6 near the base of the pressing member 5 comes into contact with the outer periphery of the pipe body 2 and stops. If the screw 8 is further screwed in with the rotation of the pressing member 5 stopped, the pressing member 5
Slides in the direction of the flange 3, the leading end of the pressing member 5 abuts against the surface member X, and the leading end of the abutting pressing member 5 and the flange 3
The surface member X in the vicinity of the outer periphery of the ventilation hole Z is sandwiched and fixed therebetween. That is, it is provided in the vicinity of the outer periphery of the pipe body 2 near the flange 3 and is formed so as to be rotatable in a direction perpendicular to the axial direction of the pipe body 2 with a predetermined position as an axis, and the tip is a free end, The pressing member 5 is protruded and retracted in the notch hole 4 as it rotates, and is slidable in the axial direction of the pipe body 2. The flange 3 is screwably or insertably attached to a hole 3a provided at a predetermined position of the flange 3 and has a tip portion provided at a predetermined position of the pressing member 5 at the hole 3a.

When the screw 8 is further screwed in, the pressing member 5 is pulled in the direction of the flange 3 along with the rotation stopping member 6a, and comes into contact with the surface member near the outer periphery of the opening Z and stops. Further, it is also possible to provide a second streak-like projection 6b which sandwiches the pressing member 5 between the rotation stopping member 6a and which slides along the other side of the pressing member 5. That is, the pressing member 5 slides between the rotation stop member 6a and the second streak projection, and the rotation stop member 6a and the second streak projection 6
b serves as a guide when the pressing member 5 is pulled in the direction of the flange 3 by the screw 8, and its shape is not limited to what is shown.

Since the pipe 1 for mounting a ventilation fan, a hood, or the like having the above-described configuration, unlike the conventional pipe body, the surface member X on the indoor side of the ventilation hole Z near the outer periphery of the ventilation hole Z is different from the conventional pipe body. There is no element that reduces the strength, and a heavy motor-driven ventilation fan weighing about 500 grams can now be securely mounted on a wall or ceiling. Further, a slit 7 is provided at the tip of the pressing member 5, a second screw 9 is inserted or screwed into the flange 3, and the tip of the second screw 9 is screwed into the slit 7. The outer peripheral portion of the ventilation hole Z of the surface member X on the indoor side of the ventilation hole Z is securely and firmly held between the distal end portion of the pressing member 5 and the flange 3 by the second screw 9. The main body 2 is securely fixed. Therefore, even if the heavy electric ventilation fan Y is attached to and inserted into the pipe main body 2, the surface member X on the indoor side is safe without being damaged. Further, since the slit 7 of the wall member 5 to which the tip of the second screw 9 is screwed is not a mere hole but a long hole having a predetermined length, it is very convenient because it can cope with the difference in models between manufacturers. is there. Not surprisingly,
Since the sealing member 10 is provided to seal the hole 4 of the pipe main body 2, the air exhausted outside by the electric ventilation fan Y does not escape to the inside of the wall in the middle of the pipe main body 2 and is very efficient. .

[Embodiment 2] FIG. 7 is an exploded perspective view of this embodiment, and FIG. 8 is an explanatory sectional view taken along the line BB of FIG.

FIG. 14 is an explanatory longitudinal sectional view of a state where
FIG. 11 is an explanatory longitudinal sectional view showing a state in which a pipe body is inserted into the discharge hole of FIG. 10, a screw and a second screw are screwed in, and an outer peripheral portion of the discharge hole of the inner wall member is sandwiched between a distal end portion of a pressing member and a flange. The next embodiment will be described with reference to FIGS. The main difference from the above-described embodiment is that the notch 4 along the outer periphery of the pipe body 2 is eliminated, and the shape of the pressing member 5 is changed. The changed pressing member 11 has the following shape. That is, the base of the pressing member 11 is fixed to the outer periphery of the pipe body 2 in the vicinity of the flange 3, the hinge 12 is provided near the base, and the free end of the tip of the pressing member 11 is radiated from the axis of the pipe body 2 in the radial direction. To be rotatable. A slit 13 is provided on the free end side of the distal end of the pressing member 11 as in the above embodiment. A bending portion is provided adjacent to the hinge portion of the pressing member, and the bending portion is provided with an opening in the longitudinal direction of the pressing member. A turning piece 16 having a part of a columnar outer periphery that swingably contacts the inner surface of the curved portion 14 is formed. The turning piece 16 is rotatably provided on the inner surface of the bending portion 14, and the tip of the screw 8 is formed to be screwable. Since it is a pipe for attaching a ventilation fan, a hood, or the like having the pressing member 11 having such a configuration, the same operation and effect as those of the first and second embodiments can be obtained.

Although not shown, the hinge 12 near the base of the pressing member 11 can be eliminated, and the base of the pressing member 11 can be formed rotatably on the outer periphery of the pipe body 2. The distal end of the member 11 (or 5) pivots radially from the axis of the pipe body 2 and the pressing member 1
If the wall member X in the vicinity of the outer periphery of the exhaust hole Z on the indoor side can be sandwiched between the front end portion of 1 (or 5) and the flange 3,
Any shape may be used regardless of the shape shown and described.

Example 4 FIG. 15 is a longitudinal sectional view showing a state in which an electric ventilation fan is mounted on the indoor side of a pipe body inserted into a ventilation hole and a hood is mounted on the outdoor side, and FIG. 16 is inserted into the ventilation hole. It is a longitudinal cross-sectional view which shows the state which attached the flexible duct to the indoor side of the pipe main body, and attached the hood to the outdoor side.

In each of the above embodiments, as shown in FIG. 15, the electric ventilation fan Y is mounted on the flange 3 of the pipe body 2 in which the flange 3 is inserted into the ventilation hole Z with the flange 3 facing the indoor side. 16 illustrates a state in which the hood Y1 is attached to the side of the pipe body 2.

A flexible duct Y2 can be attached to the other end of the pipe body 2. Although not shown, conventionally, since the diameter of the pipe main body 2 and the flexible duct Y2 are the same, the openings of the pipe main body 2 and the flexible duct Y2 abut on each other and are connected with an adhesive tape or the like. However, since the flexible duct Y2 is flexible as the name suggests, it was very difficult to connect. Therefore, the inventor inserts the other end of the pipe body 2 and one end of the flexible duct Y2 from opposite directions,
A cylindrical body 20 having a diameter capable of contacting the openings of the pipe body 2 and the flexible duct Y2 was formed. The other end of the pipe body 2 is inserted into an opening 20a at one end of the cylindrical body 20 and bonded with an adhesive (not shown) so as to prevent air from leaking, and a flexible duct is inserted into the opening 20b at the other end of the cylindrical body 20. If one end of Y2 is inserted and bonded with an adhesive or an adhesive tape (not shown) so that air does not leak, the work efficiency is greatly improved.
