PROBLEM TO BE SOLVED: To provide an air-conditioning duct structure capable of achieving a high sound absorption performance without being subjected to restriction on outer peripheral surface area of a duct as well as being manufactured at a low cost.SOLUTION: An air-conditioning duct structure comprises a duct 10 for flowing an air-conditioned air. Around the outer periphery of the duct 10, wound is a sound absorbing material 11, which is longer than an outer peripheral length of the duct 10, as well as flexible, with at least an outer periphery of the sound absorbing material 11 exposed to outside, and with both end portions 11a, 11b of the wound sound absorbing material 11 in the winding direction, connected together.SELECTED DRAWING: Figure 2

    【課題】ダクトの外周面の面積の制限を受けずに高い吸音性能を発揮させることができ、しかも、低コストである空調用ダクト構造を提供する。【解決手段】空調風を流すダクト10の外周に、ダクト10の外周長よりも長く、且つ、柔軟性を有する吸音材11の外周面が少なくとも外部に露出する状態で巻き付け、巻き付けた吸音材11の巻き付け方向の端部11a、11b同士を接続することで吸音材11をダクト10に取り付けた。【選択図】図2
