Abstract:
An inside/outside air switching device for a vehicle, comprising:an inside/outside air switching box having an inside air suction port from which inside air inside a passenger compartment of the vehicle is introduced, and an outside air suction port from which outside air outside the passenger compartment is introduced; a rotary door for selectively opening and closing the inside air suction port and the outside air suction port, the rotary door being disposed in the inside/outside air switching box to be rotatable around a rotation center axial line; and a seal member provided at a position around the rotation center axial line, for sealing the inside/outside air switching box in an axial direction, wherein: the rotary door includes an outer wall plate extending in a rotation direction of the rotary door, and both side wall plates extending from both end portions of the outer wall plate in an axial direction toward the rotation center axial line, respectively; the rotary door is disposed to be elastically deformable in such a manner that at least both parts of the side wall plates around the rotation center axial line are displaced away from each other by a dynamical pressure of a vehicle travelling, applied to the outer wall plate, in an inside air mode where the rotary door closes the outside air suction port and opens the inside air suction port; and the seal member press-contacts an inner surface of the inside/outside air switching box when at least both the parts of the side wall plates around the rotation center axial line are displaced away from each other by a predetermined distance.
