PURPOSE:To easily attain a semi-internal air mode, by moving a flexible film- shaped member being placed in an opposed condition to inside and outside air introducing ports in a case, which communicates with a blower, so as to small decrease control force of a damper while to prevent the damper from generating its tapping noise. CONSTITUTION:An air conditioning device is equipped with a blower 1 and an inside and outside air switching mechanism 3 or the like, further the inside and outside air switching mechanism 3 is equipped with a case 20 mounted to a scroll case 4 of the blower 1. Here the case 20 movably supports to its inside a flexible film-shaped member, that is, a film damper 25 through a supporting frame 26. While the case 20 provides in its side surface a shaft driving mechanism 43 which drives a driving shaft 33 to be rotated. And the shaft driving mechanism 43 provides a pinion 47 equipped with a protrusion inserted into a hole in the end part of the driving shaft 33 through a hole of the case 20. In this way, the air conditioning device, moving the film damper 25 by the shaft driving mechanism 43, opens and closes inside and outside air introducing ports 21, 22 of the case 20. |
