To provide an inspection port in which a structure of a member interposed between an outer frame and an inner frame is further simplified while preventing a track at an end portion from turning around to a back face side when an inner frame is opened.SOLUTION: An inspection port comprises: a rectangular outer frame fixed to an opening provided in an installation surface; an inner frame installed inside the outer frame; a pair of hinge members connecting the outer frame with the inner frame and pivotally mounting the inner frame so as to rotate; and a cover member mounted inside the inner frame. The pair of hinge members are mounted in the vicinity of both ends of one side of the outer frame, and each of them includes: a mounted portion fixed in the vicinity of an end of the one side of the outer frame; a connecting portion in which an outer edge of the mounted portion is bent inward; a support portion extending from a front side end of the connecting portion in a front side direction when a side where the inside is opened is a front side and an opposite side to the front side is a rear side with respect to the installation surface; and a rotating shaft connecting the support portion with the inner frame.SELECTED DRAWING: Figure 2
【課題】内枠を開放する際に端部の軌道が裏面側に回り込むことを回避しつつ、外枠と内枠とを介装する部材の構造をより簡素化した点検口を提供する。【解決手段】設置面に設けられる開口に固定される方形状の外枠と、前記外枠の内側に設置される内枠と、前記外枠と前記内枠とを連結して前記内枠を回転可能に軸止する一対のヒンジ部材と、前記内枠の内部に装着される蓋材と、を備える点検口であって、前記一対のヒンジ部材は前記外枠のうちの一辺の両端近傍に装着されるとともにその各々は、前記外枠の一辺の端部近傍に固定される取付部と、前記取付部の外側縁が内側方向に屈曲した連結部と、設置面に対し、前記内側が開放する側を表側とし、かつ、その反対側を裏側としたとき、前記連結部の表側端から表側方向へ延設された支持部と、前記支持部と前記内枠とを連結する回転軸と、を有する。【選択図】図２
