カバー部材５０は、図３に示すように、室内側の被保持部５２を第１溝部６２に挿入して先端を第１保持部６８に係合させるとともに、室外側の被保持部５３を第２溝部６５に挿入して先端を第２保持部６９に係合させることで、取付部材６０に保持されるようになっている。また、上面部５１の室外側端縁を押して上面部５１を上方凸に撓ませ、室外側の被保持部５３を第２保持部６９から外してから、室内側の被保持部５２を第１保持部６８から外すことで、カバー部材５０が取付部材６０から取り外せるようになっている。また、カバー部材５０を取り付けた状態において、その上面部５１の室内側端縁と室内レール部３８とは所定距離だけ離れ、それらの間に隙間が形成され、上面部５１の室外側端縁と室外レール部４８とは所定距離だけ離れ、それらの間に隙間が形成されるようになっている。従って、カバー部材５０が夏季の日射で加熱されたり、冬季に冷却されたりしても、その熱が下枠３に伝達されず、下枠３の断熱性能が阻害されないようになっている。 As shown in FIG. 3, the cover member 50 inserts the indoor-side held portion 52 into the first groove portion 62 to engage the tip with the first holding portion 68, and the outdoor-side held portion 53. By being inserted into the two groove portions 65 and engaging the tip with the second holding portion 69, the mounting member 60 holds the tip. Further, the outdoor side edge of the upper surface portion 51 is pushed to bend the upper surface portion 51 upward and the outdoor held portion 53 is removed from the second holding portion 69, and then the indoor held portion 52 is moved to the first. The cover member 50 can be removed from the attachment member 60 by being removed from the holding portion 68. Further, in the state where the cover member 50 is attached, the indoor side edge of the upper surface portion 51 and the indoor rail portion 38 are separated by a predetermined distance, and a gap is formed between them. The outdoor rail portion 48 is separated by a predetermined distance, and a gap is formed between them. Therefore, even if the cover member 50 is heated by solar radiation in the summer or cooled in the winter, the heat is not transmitted to the lower frame 3 so that the heat insulation performance of the lower frame 3 is not hindered.
