PROBLEM TO BE SOLVED: To provide a floor inspection port that enables a packing to be fitted readily and held firmly, and enhances waterproofing and deodorizing functions.SOLUTION: A floor inspection port includes an outer frame 10 fitted in an opening part 2 of a floor part 1, a cover body 30 having an inner frame 20 fitted on a peripheral edge, the inner frame being fitted detachably inside the outer frame, and a packing material 40 fitted on a cover body receiving part 12 provided on the outer frame and press-contacting the cover body. The cover body receiving part comprises a horizontal piece 15 extending at a bottom edge of a vertical wall 11 of the outer frame, a vertical piece 16 rising from an inner edge of the horizontal piece 15, and an upper horizontal piece 17 extending at a top edge of the vertical piece. The vertical wall, the horizontal piece, the vertical piece and the upper horizontal piece form a packing fitting part 19 that opens upward. The packing material is formed to be elastic and endless, with a stepped cross-section and a cut-out corner part. A protrusion 41 of the packing material is brought in contact with an undersurface side of the upper horizontal piece, while the other protrusion 42 is held in an engaged state with a top edge protruding outward than the upper horizontal piece.SELECTED DRAWING: Figure 2
【課題】パッキンの取付を容易にし、保持を強固にすることができ、防水・防臭機能の向上が図れる床点検口を提供する。【解決手段】床部１の開口部２内に取り付けられる外枠１０と、外枠内に着脱可能に嵌合する内枠２０を周縁に装着する蓋体３０と、外枠に設けられた蓋体受け部１２に装着され、蓋体に圧接するパッキン材４０と、を具備する床点検口において、蓋体受け部は、外枠の垂直壁１１の下端に延在する水平片１５と、水平片１５の内側端から起立する垂直片１６と、垂直片の上端に延在する上部水平片１７とからなり、垂直壁、水平片、垂直片及び上部水平片とで上方が開口するパッキン取付部１９を形成する。パッキン材を、弾性を有する角部が切り欠かれた断面段状の無端状に形成し、パッキン材の一つの突部４１を上部水平片の下面側に接し、他の突部４２を上端が上部水平片よりも突出した係合状態で保持する。【選択図】図２
