PROBLEM TO BE SOLVED: To provide a lid device for opening and closing an upper opening of a space, capable of securing waterproof performance as well as allowing relatively easy opening and closing operations while making a power source unnecessary in a relatively simple configuration.SOLUTION: A lid 5 is raised by an elevating mechanism 7 and then slid, thereby opening the upper opening 1 of the space. The elevating mechanism 7 is a feed screw mechanism constituted of a screw shaft 72 and a female screw member 73, and is operated by human power using a lift handle 74. Moreover, a seal rings 9, 10 are provided with respective lips so that the lips come into contact with the lid 5 in an oblique posture.SELECTED DRAWING: Figure 2

    【課題】空間の上開口を開閉するための蓋装置において、電源を不要とするとともに比較的簡素な構成としながら、止水性能を確保するとともに比較的簡易に開閉できるようにする。【解決手段】蓋5を昇降機構7により上昇させてからスライドさせることにより空間の上開口1を開放するようになっている。昇降機構7は、ねじ軸72と雌ねじ部材73とで構成する送りねじ機構であって、リフトハンドル74を用いて人力によって作動させるようになっている。しかも、シールリング9,10は、リップ付きであって、当該リップが斜め姿勢で蓋5に接触するようになっている。【選択図】図2
