　ところで、空気調和装置を運転する場合、冷房運転時においては、吹出口から冷風が吹出されるため、吹出口近傍のパネル本体および断熱部材の温度が低下する。また、暖房運転時には、吹出口から温風が吹出されるため、吹出口近傍のパネル本体および断熱部材の温度が上昇する。
　これらパネル本体および断熱部材は、温度の低下または上昇にともない、収縮または膨張する。 By the way, when operating an air conditioner, since the cool air is blown out from the air outlet during the cooling operation, the temperatures of the panel body and the heat insulating member in the vicinity of the air outlet are lowered. Moreover, since warm air is blown out from the air outlet during the heating operation, the temperature of the panel body and the heat insulating member in the vicinity of the air outlet rises.
The panel body and the heat insulating member contract or expand as the temperature decreases or rises.

　次に、本実施形態の作用について説明する。
　空気調和装置の運転により、吸い込み口３１から吸い込まれた空気が室内ユニット１０により熱交換され、熱交換された空気は、吹出口３４から被調和室へ送られる。
　このとき、吹出口３４の近傍を中心として化粧パネル３０は、温度の上昇または低下に伴い膨張または収縮する。化粧パネル３０に備えられる第１のリブ４５および第２のリブ４６、断熱部材５０も、温度の上昇または低下に伴い膨張または収縮する。
　ここで、第１のリブ４５および第２のリブ４６は樹脂製であり、断熱部材５０は発泡スチロール製であるため、第１のリブ４５および第２のリブ４６と断熱部材５０とでは材質が異なり、温度の上昇または低下に伴い膨張または収縮する率が異なる。 Next, the operation of this embodiment will be described.
By the operation of the air conditioner, the air sucked from the suction port 31 is heat-exchanged by the indoor unit 10, and the heat-exchanged air is sent from the air outlet 34 to the room to be conditioned.
At this time, the decorative panel 30 expands or contracts as the temperature rises or falls with the vicinity of the outlet 34 as the center. The first rib 45, the second rib 46, and the heat insulating member 50 provided in the decorative panel 30 also expand or contract as the temperature increases or decreases.
Here, since the first rib 45 and the second rib 46 are made of resin and the heat insulating member 50 is made of foamed polystyrene, the first rib 45 and the second rib 46 and the heat insulating member 50 are made of different materials. The rate of expansion or contraction varies with increasing or decreasing temperature.

Thus, the contact area between the panel body 40 and the heat insulating member 50 is reduced.
Therefore, rubbing between the first rib 45 and the second rib 46 and the heat insulating member 50 due to a difference in expansion or contraction occurs only in a very small contact area portion.
