しないようにしている。 FIG. 1 is a sectional view showing one embodiment of the reinforcing core duct of the present invention, and is a sectional view of the conventional synthetic resin duct whose length and diameter can be adjusted as shown in FIG. A reinforcing core made of a thin metal plate is placed inside the strip. The band-shaped body 4 has a tuning-fork shape in cross section and is composed of a flat cylindrical part 2 and a flat plate-shaped part 3. The engaging part 3a is inserted into the cavity 2b of the flat cylindrical part 2 through the opening 2a, and then screwed. The point of forming a duct by winding it in a linear shape is similar to the conventional one, but approximately at the center of the flat plate part 3 is a thin metal plate (such as cemented carbide or steel) which is the gist of the present invention. ) reinforcing core 1 is inserted. Furthermore, the engaging portion 3a of the flat plate portion 3
The outer shape is circular, and the outer diameter is the same as the spacing between the spaces 2b of the flat cylindrical portion 2, or is slightly smaller. Further, the thickness of the flat plate portion 3 and the spacing between the openings 2a of the flat cylindrical portion 2 are approximately equal to prevent air, smoke, etc. inside the duct from leaking to the outside.
尚、上記実施例では、平板状部３だけに金属製

が可能となる。<Effects of the invention> As described above, the reinforcing core duct of the present invention has the following advantages:
By inserting a metal reinforcing core into the pipe wall of the synthetic resin duct, it does not interfere with the duct's expansion/contraction movement and does not deform even when hot air, exhaust gas, smoke, etc. are passed through to a certain extent. As the range of use expands, the risk of functional deterioration due to deformation is reduced. Moreover, the strength against external impact is increased, and it becomes possible to significantly improve heat resistance and strength.
