左右の両側の端部側壁３４に配置された側面断熱材３５は、ギャップカバー５０で覆われている。ギャップカバー５０は化粧パネル３と同一の材質である樹脂製であり、吹出口６の端部側壁３４に対向する風向板２６の端面２７と端部側壁３４との間に形成された隙間を目立たないようにするために、化粧パネル３と同一の色となっている。ギャップカバー５０は化粧パネル３とは別部材であって、化粧パネル３に対して取り外し可能に図示されないネジによって固定されている。ギャップカバー５０は、側壁、底面壁、上面壁を備えた断面がコの字状であって、ギャップカバー５０が化粧パネル３に固定された状態で、底面壁の外部側であるギャップカバー化粧面５１は、化粧パネル３の底面と平行で、かつ、同一面高さになるように配置され、化粧パネル３の底面側に露出する。ギャップカバー５０の底面壁と上面壁との間に配置する側壁の外部側となるギャップカバー側面５２は、風向板２６の端面２７に対向して配置される。ギャップカバー５０の内部側に側面断熱材３５が挿入され、ギャップカバー５０が化粧パネル３に固定された状態で、ギャップカバー５０の開放側に向いている側面断熱材３５の面は、吹出口６の端部側壁３４に隣接する。 The side heat insulating materials 35 disposed on the end side walls 34 on both the left and right sides are covered with gap covers 50. The gap cover 50 is made of resin, which is the same material as the decorative panel 3, and makes the gap formed between the end surface 27 of the wind direction plate 26 facing the end side wall 34 of the air outlet 6 and the end side wall 34 conspicuous. In order to avoid this, the color is the same as that of the decorative panel 3. The gap cover 50 is a separate member from the decorative panel 3, and is removably fixed to the decorative panel 3 by screws (not shown). The gap cover 50 has a U-shaped cross section including a side wall, a bottom wall, and a top wall, and when the gap cover 50 is fixed to the decorative panel 3, the gap cover decorative surface which is the external side of the bottom wall 51 is arranged parallel to and at the same height as the bottom surface of the decorative panel 3, and is exposed on the bottom surface side of the decorative panel 3. A gap cover side surface 52 , which is the outer side of the side wall disposed between the bottom wall and the top wall of the gap cover 50 , is disposed opposite to the end surface 27 of the wind direction plate 26 . When the side insulation material 35 is inserted inside the gap cover 50 and the gap cover 50 is fixed to the decorative panel 3, the surface of the side insulation material 35 facing the open side of the gap cover 50 is connected to the air outlet 6. Adjacent to the end side wall 34 of.

また、ギャップカバー化粧面５１とギャップカバー側面５２とで形成される角部には、ギャップカバー側面５２と風向板２６の端面２７との間に形成された隙間を、ギャップカバー化粧面５１側に向かって広げる拡張部としての段差部５４が形成される。図６に示すように、ギャップカバー側面５２から段差部５４におけるギャップカバー側面５２と平行な段差面までの幅は２ｍｍである。ギャップカバー側面５２から段差部５４におけるギャップカバー側面５２と平行な段差面までの幅は、ギャップカバー側面５２と平行な段差面に吹出口６からの空気流が触れにくくなる２ｍｍ以上が望ましい。 Further, at the corner formed by the gap cover decorative surface 51 and the gap cover side surface 52, a gap formed between the gap cover side surface 52 and the end surface 27 of the wind direction plate 26 is placed on the gap cover decorative surface 51 side. A stepped portion 54 is formed as an expanded portion that widens toward the surface. As shown in FIG. 6, the width from the gap cover side surface 52 to the step surface parallel to the gap cover side surface 52 in the stepped portion 54 is 2 mm. The width from the gap cover side surface 52 to the step surface parallel to the gap cover side surface 52 in the stepped portion 54 is preferably 2 mm or more, which makes it difficult for the air flow from the air outlet 6 to come into contact with the step surface parallel to the gap cover side surface 52.

側面断熱材３５は断熱性をあげるため発泡性の材料で形成されている。そのため、従来技術のようにギャップカバー５０が無い場合は、樹脂製の化粧パネル３と側面断熱材３５との質感の違いによって、端部側壁３４と端面２７との間に形成された隙間が目立ってしまうが、ギャップカバー５０を化粧パネル３と似た素材を用いれば、側面断熱材３５をギャップカバー５０で覆う場合は、端部側壁３４と端面２７との間に形成された隙間を目立たないようにすることができる。 The side heat insulating material 35 is made of a foaming material to improve heat insulation. Therefore, when there is no gap cover 50 as in the prior art, the gap formed between the end side wall 34 and the end surface 27 becomes noticeable due to the difference in texture between the resin decorative panel 3 and the side insulation material 35. However, if the gap cover 50 is made of a material similar to that of the decorative panel 3, when the side insulation material 35 is covered with the gap cover 50, the gap formed between the end side wall 34 and the end surface 27 can be made less noticeable. You can do it like this.

また、ギャップカバー化粧面５１とギャップカバー側面５２とで形成される角部には段差部５４が形成されているので、吹出口６の端部側壁３４に沿って下方に向かって吹き出される冷却された空気流は、段差部５４に至った後もそのまま下方に向かって吹出される。そのため、段差部５４は冷却された空気流に触れにくくなるため、結露が発生しにくくなる。その結果、ギャップカバー化粧面５１にも結露が発生しにくくなるので、汚れが付着することを抑制することができる。 In addition, since a stepped portion 54 is formed at the corner formed by the gap cover decorative surface 51 and the gap cover side surface 52, cooling is blown out downward along the end side wall 34 of the air outlet 6. Even after reaching the stepped portion 54, the airflow is blown out downward as it is. Therefore, the stepped portion 54 is less likely to come into contact with the cooled airflow, and therefore dew condensation is less likely to occur. As a result, since dew condensation is less likely to occur on the gap cover decorative surface 51, it is possible to suppress the adhesion of dirt.

ギャップカバー５０は化粧パネル３に取り外し可能であり、化粧パネル３とは別部品であるため、ギャップカバー５０に汚れがついて目立ってしまう場合などは、交換が容易である。また、ギャップカバー５０に段差部５４を設ける場合は成形が容易である。 Since the gap cover 50 is removable to the decorative panel 3 and is a separate component from the decorative panel 3, it can be easily replaced if the gap cover 50 becomes dirty and noticeable. Furthermore, when the gap cover 50 is provided with the stepped portion 54, molding is easy.

本実施形態では、ギャップカバー５０に拡張部として段差部５４を設けたが、ギャップカバー側面５２と風向板２６の端面２７との間に形成された隙間を、ギャップカバー化粧面５１側に向かって広げる形状であれば、段差部５４である必要はなく、例えば、ギャップカバー側面５２とギャップカバー化粧面５１との間を斜面で形成する、いわゆる、面取り、または、Ｒ状に仕上げるＲ面取りであっても構わない。面取りの幅は、少なくとも２ｍｍ以上が望ましい。 In this embodiment, the gap cover 50 is provided with the stepped portion 54 as an expanded portion, but the gap formed between the gap cover side surface 52 and the end surface 27 of the wind direction plate 26 is extended toward the gap cover decorative surface 51 side. As long as it has a widening shape, it does not need to be the stepped portion 54, and for example, it may be a so-called chamfer that forms a slope between the gap cover side surface 52 and the gap cover decorative surface 51, or an R-chamfer that is finished in an R shape. I don't mind. The width of the chamfer is preferably at least 2 mm or more.
