Abstract
In an air passage opening/closing device for a vehicle air conditioner, a driving member is disposed to apply driving force for a reciprocating movement of a film member to at least one position of the film member, and a guide member is provided in an air-conditioning case to guide the reciprocating movement of the film member. The film member has a flexible performance to move in a bend path, and has a rigidity to be moved along the guide member when pushing force from the driving member is applied to the film member. Thus, the air passage opening/closing device using the film member has a simple structure without a film-winding mechanism.
