Abstract
An air passage opening/closing device includes a film member for opening and closing an opening of an air passage of a case. One end of the film member is fixed to a fixing portion on an outer periphery of the opening of the air passage, and the other end thereof is connected to a film winding shaft. A moving member movable by rotation of a drive shaft is provided on the opening, and the film winding shaft is moved while being rotated by the movement of the moving member, so that the film member at the other end side is wound around and unwound from the film winding shaft. Accordingly, when the air passage is opened and closed by the film member, sliding friction can be prevented from being generated between the film member and the case.
