て、その伸びが吸収されることになる。When actually mounting the protection plate 21 in the duct body 2, as shown in FIGS. 2 and 4, the protection plate 21 having a predetermined length is sequentially arranged along the longitudinal direction of the duct 1. At this time, for example, the opposing end portions of the pair of protective plates 21 adjacent to each other in the longitudinal direction are overlapped with each other to form the free end a, and the other end portion is the fixed end b. . Therefore, when the protective plate 21 expands in the longitudinal direction due to thermal expansion, the expansion is absorbed at the free end a.
