る。(Solution Means, Actions and Effects) A pipe of the present invention is a cylindrical main body having a pair of edges that define a continuous gap from one end to the other end in the longitudinal direction of the main body, It includes a first member fixed inside the main body portion and extending in the longitudinal direction of the main body portion, and a second member fixed outside the main body portion and extending in the longitudinal direction of the main body portion. The first member defines a void, which is communicated around the main body portion through the gap, with the both edges of the main body portion inside the main body portion. The second member is a plate-shaped first portion having a thickness smaller than the width of the gap, the first portion being fixed to the main body portion at one widthwise end edge thereof, and the first portion. A second portion having a cross-sectional shape larger than the width of the gap and smaller than the gap, the second portion being fixed to the other edge in the width direction of the portion.
