To provide an inspection port that does not require a space for sliding on a side of an inner lid when attaching/detaching an inner lid to/from an outer frame.SOLUTION: An inner lid 6 is attached to an outer frame 4 attached to a ceiling material 2 via a hinge device 5 so as to be freely opened and closed. The hinge device 5 has an outer frame hinge 30 provided on the outer frame 4 and an inner frame hinge 31 provided on an inner frame 8 of the inner lid 6. The inner frame hinge 31 can be freely engaged with and disengaged from the outer frame hinge 30 in an engagement and disengagement direction 11 that intersects a longitudinal direction of the outer frame hinge 30. An anti-fall-off member 40 that prevents the inner lid 6 from falling off from the outer frame 4 is provided on the outer frame 4. The anti-fall-off member 40 is switchable between an inner lid fall-off prevention position that prevents the inner frame hinge 31 from detaching from the outer frame hinge 30, and an inner lid attachment and detachment position. In the inner lid fall-off prevention position, the inner frame hinge 31 engaged with the outer frame hinge 30 with the inner lid 6 open is restricted from moving in a detachment direction 11a detaching from the outer frame hinge 30.SELECTED DRAWING: Figure 5
【課題】内蓋を外枠に着脱する際、内蓋の側方にスライド用のスペースを確保する必要がない点検口を提供する。【解決手段】天井材２に取付けられた外枠４に、内蓋６がヒンジ装置５を介して開閉自在に取付けられ、ヒンジ装置５は、外枠４に設けられた外枠ヒンジ３０と、内蓋６の内枠８に設けられた内枠ヒンジ３１とを有し、内枠ヒンジ３１は外枠ヒンジ３０の長さ方向に交差する係脱方向１１において外枠ヒンジ３０に係脱自在であり、内蓋６が外枠４から脱落するのを防止する脱落防止部材４０が外枠４に設けられ、脱落防止部材４０は、内枠ヒンジ３１が外枠ヒンジ３０から離脱するのを阻止する内蓋脱落防止位置と、内蓋着脱位置とに切替え可能であり、内蓋脱落防止位置において、内蓋６を開いた状態で外枠ヒンジ３０に係合している内枠ヒンジ３１が外枠ヒンジ３０から離脱する離脱方向１１ａへ移動するのを規制する。【選択図】図５
