CASING
PROBLEM TO BE SOLVED: To provide a casing capable of easily preventing floatation of a cover, and easy in installation work and removal work of a cover body.SOLUTION: A casing comprises a body for storing an underground structure on the inside and having an opening part on the upper side, and a cover body detachably installed in the body and opening-closing the opening part by rotation around the base end side. The cover body comprises a pair of first engaging parts forming a pair of first concave parts positioned on the base end side and opening to mutually opposite sides of the outer periphery of the cover body, and a pair of second engaging parts forming a pair of second concave parts positioned on the other end side and opening to mutually opposite sides of the outer periphery of the cover body. The body comprises mutually opposed two sets of convex parts of projecting from an inside surface, and of the two sets of convex parts, any one set guides rotation of the cover body by engaging with the first concave part, and the other set engages with the second concave part. The first engaging part and the second engaging part comprise energization means movable to the inside to the outer periphery of the cover body and energizing to the outside, and move to the inside by abutting on the convex part and move to the outside by an abutment release.SELECTED DRAWING: Figure 1
【課題】簡易に蓋の浮上防止が可能で蓋体の取付作業および取外作業が容易な筐体を提供する。【解決手段】内部に地下構造物を収納し上側に開口部を有する本体と、該本体に脱着可能に取り付けて基端側を中心とする回動により開口部を開閉する蓋体とを備え、蓋体は、基端側に位置し蓋体の外周の互いに逆側に開口する一対の第１の凹状部を形成する一対の第１の係合部と、他端側に位置し蓋体の外周の互いに逆側に開口する一対の第２の凹状部を形成する一対の第２の係合部とを有し、本体は、内側面から突出し互いに対向する２組の凸状部と、を有し、２組の凸状部のうち何れか一方は第１の凹状部と係合し蓋体の回動をガイドし、他方は第２の凹状部と係合し、第１の係合部および第２の係合部は、蓋体の外周に対し内側に移動可能であり、かつ外側に付勢する付勢手段を有し、凸状部と当接することで内側に移動し当接解除によって外側に移動する。【選択図】図１
