Zusammenfassung:	To prevent a link member from being broken and hold an inside/outside air switching damper in a prescribed position even if an output shaft is rotated for a prescribed time or more when an electric actuator is broken.SOLUTION: When an actuator side link member 30 rotates until exceeding a rotation position of an outside air introduction mode, a blower device for vehicle air conditioning causes a damper side link member 40 to withdraw from the actuator side link member 30 and engages the damper side link member 40 that has withdrawn from the actuator side link member 30 with a blower air casing 10.SELECTED DRAWING: Figure 7 【課題】電動アクチュエータの故障時に出力軸を所定時間以上回動させた場合であっても、リンク部材の破損を防止し、内外気切替ダンパを所定位置で保持できるようにする。【解決手段】アクチュエータ側リンク部材３０が、外気導入モードの回動位置を超えるまで回動したときに、ダンパ側リンク部材４０をアクチュエータ側リンク部材３０から離脱させる。アクチュエータ側リンク部材３０から離脱したダンパ側リンク部材４０を送風ケーシング１０に係合させる。【選択図】図７
