<P>PROBLEM TO BE SOLVED: To provide a split type duct in which shapes of a first split body and a second split body and assembling positions can be easily adjusted, and which facilitates assembling work. <P>SOLUTION: The split type duct is composed of a first split body 1 that is a non-air-permeable member and a second split body 2 that is an air-permeable member. A first mounting portion is disposed on at least one of circumferential ends of a circumferential wall portion 3 of the first split body 1, the mounting portion protruding outward from the duct; and a first flange portion is disposed on the top end of the first mounting portion. A second mounting portion is disposed on at least one of circumferential ends of a circumferential wall portion 6 of the second split body 2, the second mounting portion in a folded shape toward an outer circumferential face side of the circumferential wall portion 6; and a second flange portion is disposed on the top end of the second mounting portion. In an assembled state, the second mounting portion is elastically in contact with the first mounting portion in such a manner that a second inner face 71 continuing to the inner circumferential face of the second circumferential wall portion 6 in the second mounting portion opposes to a first inner face continuing to the inner peripheral face of the first peripheral wall portion 3 in the first mounting portion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
