LID RECEIVING FRAME SET FOR UNDERGROUND STRUCTURE
To provide a lid receiving frame set for an underground structure which is devised to swing a regulation member without catching a valve body at an inner peripheral surface of a receiving frame.SOLUTION: A regulation member 6 has a valve body 61 for blocking a keyhole 4a and an axis 62. The valve boy 61 is energized in a direction for blocking the keyhole 4a. A lock member 5a has a claw part 53 which is engaged with a claw receiving part 32 and blocks opening of an opening, and is swung in a state of being not engaged with the claw receiving part 32, thereby, permits opening of the opening. When the regulation member 6 is swung in a direction for opening blocking of the keyhole 4a with the valve body 61, the tip of the valve body 61 is brought into contact with an inner peripheral surface 31 of a receiving frame 3, and the axis 62 is moved in a direction separated from the inner peripheral surface 31.SELECTED DRAWING: Figure 7
【課題】弁体が受枠の内周面に引っかかってしまうことなく、規制部材を揺動させることができる工夫がなされた地下構造物用蓋受枠セットを提供する。【解決手段】規制部材６は、鍵穴４ａを閉塞する弁体６１と、軸６２とを有し、弁体６１が鍵穴４ａを閉塞する方向に付勢されたものであり、錠部材５は、爪部５３が爪受け部３２に係合して開口の開放を阻止する一方、爪部５３が爪受け部３２に係合しない状態に揺動させると開口の開放を許容するものであり、規制部材６を弁体６１が鍵穴４ａを閉塞する状態から開放する方向に揺動させると、弁体６１の先端が受枠３の内周面３１に接触し、軸６２が内周面３１から離れる方向に移動するものである。【選択図】図７
