To make an initial opening holding device of an inspection port as compact as possible, and to enhance reliability of an operation.SOLUTION: An inspection port includes: an outer frame 3 in which an inspection opening 6 is partitioned by a surface side frame part inner part 12a; a lid body 4 supported by the outer frame 3; a lock mechanism 30 for locking/unlocking in a state where the lid body 4 is closed; and an initial opening holding device 40 for restricting an opening operation of the lid body 4 on the way. The initial opening holding device 40 includes: a fixing plate part 41 fixed to an erected wall part 21 of the lid body 4; an operation plate part 42 folded downward from an upper end part of the fixing plate part 41; a locking plate part 43 which is folded to the fixing plate part 41 from a lower end part of the operation plate part 42, and in a state where the inspection opening 6 is closed by the lid body 4, which is positioned in an upper region of the surface side frame part inner part 12a; and a lock releasing plate part 44 suspending from the locking plate part 43.SELECTED DRAWING: Figure 5
【課題】点検口の初期開き保持装置において、極力コンパクトにすると共に、作動の信頼性を高める。【解決手段】表面側フレーム部内方部１２ａが点検開口６を区画する外枠３、外枠３に支持される蓋体４、蓋体４を閉じた状態でロック、アンロックするロック機構３０、蓋体４の開動作を途中で規制する初期開き保持装置４０を備える。初期開き保持装置４０は、蓋体４の起立壁部２１に固定される固定板部４１、固定板部４１の上端部から下方に折り返される作動板部４２、作動板部４２の下端部から固定板部４１に折り返され、点検開口６が蓋体４により閉じた状態のとき、表面側フレーム部内方部１２ａの上方領域に位置する係止板部４３、係止板部４３から垂下する係止解除板部４４を備える。【選択図】 図５
