UNDERGROUND STRUCTURE PROTECTION BOX
PROBLEM TO BE SOLVED: To provide an underground structure protection box capable of facilitating a cover body attachment/detachment operation.SOLUTION: An underground structure protection box 1 includes a box body 3 and a cover body 4 that is detachably attached to the box body 3. The cover body 4 makes a top surface opening 2 of the box body 3 opened/closed by rotation centering on the side of a base end. The cover body 4 has a concave part 12 provided on the side of the base end. The box body 3 has an elastically-deformable anti-coming-off convex part 36 that is engaged with the concave part 12 to prevent the cover body 4 from coming off from the box body 3.
【課題】蓋体の取付作業および取外作業を容易にできる地下構造物保護箱を提供する。【解決手段】地下構造物保護箱１は、箱本体３と、この箱本体３に脱着可能に取り付ける蓋体４とを備える。蓋体４は、基端側を中心とする回動により箱本体３の上面開口部２を開閉する。蓋体４は、凹状部12を基端側に有する。箱本体３は、凹状部12との係合により蓋体４の箱本体３からの抜けを防止する弾性変形可能な抜け防止用の凸状部36を有する。【選択図】図１
