OPENING/CLOSING DEVICE OF MANHOLE COVER
PROBLEM TO BE SOLVED: To provide an opening/closing device of a manhole cover which enables a manhole cover to be revolved keeping the horizontal state by revolution of an attachment bracket and also enables a height of a position of the manhole cover to be easily adjusted according to various locations when the manhole cover is removed from a manhole.SOLUTION: A opening/closing device of a manhole cover 100 includes: a manhole 2; a ring-shaped member 3; a packing 4; a manhole cover 5; a pressing member 6; a handle 7; a screw shaft 8; a support bracket 20; an attachment bracket 22; a pair of upper and lower arms 25, 26; and a rotation range adjustment part 40.
【課題】取付ブラケットの旋回により水平状態のまま旋回させることができるだけでなく、マンホールから取り外した際のマンホールカバーの位置の高さを、様々な場所に合わせて容易に調整することが可能なマンホールカバーの開閉装置を得る。【解決手段】マンホールカバーの開閉装置１００は、マンホール２と、リング状部材３と、パッキン４と、マンホールカバー５と、押圧部材６と、ハンドル７と、スクリュー捻子軸８と、支持ブラケット２０と、取付ブラケット２２と、上下一対のアーム２５，２６と、回動範囲調整部４０と、を備えている。【選択図】図２
