To reduce noise emitted by an air-conditioning case.SOLUTION: An air conditioner includes an air-conditioning case 10 and a motor holder 40. The motor holder 40 has a cylindrical part 41 which is cylindrical, a cylindrical duct part 42, and a cylindrical air introduction port 43. The air-conditioning case 10 has a cylindrical air passage formation part 190. An inner peripheral surface of the air passage formation part 190 and an outer peripheral surface of the air introduction port 43 are in contact, and the air introduction port 43 is supported by and fixed to the air passage formation part 190. The outer peripheral surface of the air introduction port 43 and the inner peripheral surface of the air passage formation part 190 are inclined in the way that they go away from a center line 18a of an air passage 18 as a cross-sectional shape of a cross section including the center line 18a of the air passage 18 moves in the direction in which it goes away from a ventilation trunk 11 of center line 18a directions of the air passage 18.SELECTED DRAWING: Figure 5 【課題】空調ケースから放射される騒音を低減する。【解決手段】空調装置は、空調ケース１０とモータホルダ４０を備える。モータホルダ４０は、筒状の筒状部４１、筒状のダクト部４２および筒状の空気導入口４３を有し、空調ケース１０は、筒状の空気通路形成部１９０を有している。空気通路形成部１９０の内周面と空気導入口４３の外周面とが接触して空気導入口４３が空気通路形成部１９０に支持固定される。空気導入口４３の外周面および空気通路形成部１９０の内周面は、空気通路１８の中心線１８ａを含む断面の断面形状が空気通路１８の中心線１８ａ方向のうち通風路１１から離れる方向に進むにつれて空気通路１８の中心線１８ａから離れるよう傾斜している。【選択図】図５
