Air passage switching device and air conditioning apparatus using the same

摘要

In switching of opening and closing air passage opening portions of an automotive air conditioning apparatus, a circumference one end of the film member (92) is secured to one end in a circumferential direction of the rotary door (91) by a pin member (91i), and the other end in a circumferential direction of the film member (92) is set to be a free end (92d) which is movable with reference to a slide wall portion (91h) of the rotary door (91). The variation in dimension of the film member (92) or the case (1) side is absorbed by movement of the free end (92d), and the occurrence of defective seal and noise is prevented. <IMAGE>
