To provide an inspection port that can be installed even if there is not enough space on the rear side of an installation surface and has a compact structure around the moving shaft.SOLUTION: An inspection port provided with an outer frame and a rotatable inner frame, the outer frame provided with an outer frame vertical piece that is perpendicular to an installation surface, an outer frame proximal flange portion that is provided to extend inward from a proximal end of the outer frame vertical piece, an outer frame distal outward flange portion that is provided to extend outward from a distal end of the outer frame vertical piece, and an outer frame distal inward flange portion that is provided to extend inward, the inner frame provided with an inner frame vertical piece that is perpendicular to the installation surface in the closed state, an inner frame proximal flange portion that is provided to extend outward from the proximal end of the inner frame vertical piece so as to come into contact with the outer frame proximal flange portion, an inner frame distal outward flange portion that is provided to extend outward from the distal end of the inner frame vertical piece, an inner frame distal inward flange portion that is provided to extend inward, a hollow tubular shaft storage cylinder portion that is provided to extend along the longitudinal direction on the periphery near at least both the ends of one of rear sides of the inner frame distal outward flange portion, and a rotary shaft that is inserted into the shaft storage cylinder portion in a state where both the ends thereof protrude.SELECTED DRAWING: Figure 2
【課題】設置面の裏面側の空間に余裕がなくても設置可能な回動軸周りの構造がコンパクトな点検口を提供する。【解決手段】外枠と回動可能な内枠とを備える点検口であって、外枠は設置面に対して垂直な外枠垂直片と、外枠垂直片の近位端から内方に延設される外枠近位フランジ部と、外枠垂直片の遠位端から外方に延設される外枠遠位外方フランジ部及び内方に延設される外枠遠位内方フランジ部と、を備え、内枠は閉鎖状態で設置面に対して垂直な内枠垂直片と、内枠垂直片の近位端から外方に延設され外枠近位フランジ部と当接する内枠近位フランジ部と、内枠垂直片の遠位端から外方に延設される内枠遠位外方フランジ部及び内方に延設される内枠遠位内方フランジ部と、内枠遠位外方フランジ部のうちの一つの裏面側の少なくとも両端近傍の辺縁に長手方向に沿って延設される中空管状の軸収容筒部と、前記軸収容筒部に両端が突出する状態で挿入される回動軸とを備える。【選択図】図２
