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
