INSPECTION PORT DEVICE
PROBLEM TO BE SOLVED: To easily open-close a cover part, while covering-hiding a fastening member by the cover part, in an inspection port device fixed to a backing material by the fastening member.SOLUTION: An inspection port device comprises a frame member and a lid member arranged so as to block up an inspection port, in which the frame member includes a bottom wall part fixed to a backing material by a fastening member, an inside wall part of extending to the indoor side from an edge part on the inspection port central side of the bottom wall part, an outside wall part of extending to the indoor side from an edge part on the distant side from the inspection port center in the bottom wall part, a projection piece of projecting to the inside wall part side from an inner wall surface of the outside wall part, a lid support part for supporting a peripheral edge part of the lid member and a cover part for covering the fastening member from the indoor side by blocking up an opening between the inside wall part and the outside wall part, and the cover part includes a cover part body and a projection part engageably-disengageably engaging with the projection piece by projecting from the cover part body, and the projection part includes a base part of projecting to the bottom wall part side from the cover part body and a swelling part of swelling in a cross-sectional circular arc shape to the projection piece side from a side surface on the tip side of the base part.SELECTED DRAWING: Figure 5
【課題】下地材に締結部材で固定された点検口装置において、カバー部で締結部材を覆い隠すことができるとともにカバー部の開閉を容易に行うこと。【解決手段】枠部材と、点検口を塞ぐように配置される蓋部材とを備え、枠部材は、下地材に締結部材で固定される底壁部と、底壁部の点検口中心側の縁部から室内側に延出する内側壁部と、底壁部における点検口中心から遠い側の縁部から室内側に延出する外側壁部と、外側壁部の内壁面から内側壁部側に突出する突片と、蓋部材の周縁部を支持する蓋支持部と、内側壁部と外側壁部との間の開口を閉塞することにより締結部材を室内側から覆うカバー部とを含み、カバー部は、カバー部本体と、カバー部本体から突出して突片と係脱可能に係合する凸部とを含み、凸部は、カバー部本体から底壁部側に突出する基部と、基部の先端側の側面から突片側に断面円弧状に膨出する膨出部とを含む。【選択図】図５
