INSPECTION HOLE
PROBLEM TO BE SOLVED: To provide an inspection hole that makes a sheet material such as a light diffusion sheet hardly get wrinkles and that does not deteriorate beauty even when being affected by a tensile force of the sheet material.SOLUTION: An inspection hole 1 comprises: an outer frame 2 that is fixed to an opening H; an inner frame 3 that can be freely opened/closed in the outer frame 2; a light diffusion sheet 44 that is stretched inside the inner frame 3; and a holding member 45 for stretching the light diffusion sheet 44 inside the inner frame 3. The holding member 45 is formed like a frame. The inner frame 3 holds the holding member 45 where the light diffusion sheet 44 is stretched, and does not fix the holding member 45.
【課題】光拡散シートなどのシート材に皺が寄りにくく、シート材の張力による影響を受けても美観を損なわない点検口を提供する。【解決手段】開口部Ｈに固定される外枠２と、この外枠２に開閉自在な内枠３と、この内枠３の内側に張られる光拡散シート４４と、この光拡散シート４４を上記内枠３の内側で張るための押さえ部材４５とを備えた点検口１であって、上記押さえ部材４５が枠状に形成され、上記内枠３が、上記光拡散シート４４が張られた上記押さえ部材４５を保持するとともに、当該押さえ部材４５を固定しないものである。【選択図】図２
