<p>PROBLEM TO BE SOLVED: To restrict a plurality of ducts from generating damage at a duct structure in which a ventilation duct is constituted by connecting ducts to each other.SOLUTION: An air conditioning duct is constituted by connecting a plurality of duct segments to each other. Each of outer circumferential surfaces of adjoining duct segments 42A, 42B is respectively provided with protrusions 51A, 51B that are oppositely faced to each other. A connecting bracket 53 connecting the adjoining ducts 42 to each other is fixed to each of the opposing protrusions 51A, 51B. The connecting bracket 53 comprises: a winding segment 54 wound to each of protrusions 51A, 51B under a state in which each of the protrusions 51A, 51B is enclosed in total; and a pair of connecting ends 55a, 55b for use in fixing the connecting bracket 53 to each of the protrusions 51A, 51B that are extended from both ends of the winding segment 54 toward outside of the winding segment 54 and connected to each other.</p> |
