To provide an air filter of an air-conditioning device which can be inserted from a small insertion port, and is suppressed in air leakage.SOLUTION: A filter main body 17 is formed into a bellows structure having elasticity which can be contracted in a direction orthogonal to a filter face, a ventilation path 6 is inserted from an insertion port 16 of a ventilation case 7 in the contracted state, and an end face of an inner seal member 18 having flexibility and elasticity to a contraction direction of the filter main body is pasted to an end face of the filter main body at the insertion port side, made to firmly adhere to the inside of the insertion port 16, and sealed thereto when the ventilation path 6 is in positive pressure. Also, an outer seal member 19 having flexibility and elasticity which can firmly adhere to a port edge part of the insertion port 16 is arranged outside the inner seal member, made to firmly adhere to the port edge part of the insertion port 16 when the ventilation path 6 is in negative pressure, and sealed thereto, thus eliminating a different lid material for the insertion port.SELECTED DRAWING: Figure 4

    【課題】 小さい挿入口から挿入することができ、かつエア漏れの少ない車両用空気調和装置のエアフィルタを提供する。【解決手段】フィルタ本体17をフィルタ面と直交する方向に収縮可能な弾性を有する蛇腹構造とし、その収縮状態で通風ケース7の挿入口16から通風路6に挿入し、フィルタ本体の挿入口側の端面にはフィルタ本体の収縮方向に可撓性と弾性を有する内シール部材18の端面を貼付けて通風路6の正圧時に挿入口16の内側に密着させてシールし、また、内シール部材の外側に挿入口16の口縁部に密着可能な可撓性と弾性を有する外シール部材19を設け、通風路6の負圧時に挿入口16の口縁部に密着させてシールし、これにより、別体の挿入口用の蓋材を廃止する。【選択図】図4
