PROBLEM TO BE SOLVED: To suppress damage of the outer peripheral edge part in a cover front plate while suppressing an increase in width of a cover frame.SOLUTION: A cover 1 comprises a cover base plate 11, a cover front plate 12 arranged on the cover base plate 11, and a cover frame 13 arranged in the outer peripheral edge of the cover front plate 12 and fixed to the cover base plate 11 by a plurality of countersunk screws 16. The cover frame 13 has a cylindrical part 13a and a flange part 13b inwardly-formed at the top edge of the cylindrical part 13a and opposed to the top face 12b of the cover front plate 12 in the vertical direction. A plurality of screw holes 11d for fixing the countersunk screws 16 are formed in the outer peripheral side surface 11c of the cover base plate 11. The cylindrical part 13a has a plurality of open holes 13a1 through which the countersunk screws 16 pass formed at a position facing each of the plurality of screw holes 11d.SELECTED DRAWING: Figure 2
【課題】蓋枠の幅が大きくなるのを抑制しつつ、蓋表板の外周縁部が損傷するのを抑制する。【解決手段】蓋１は、蓋基板１１と、記蓋基板１１上に配置された蓋表板１２と、蓋表板１２の外周縁に配置され、複数の皿頭ネジ１６によって蓋基板１１と固定される蓋枠１３とを含む。蓋枠１３は、筒状部１３ａと、筒状部１３ａの上端に内向きに形成され蓋表板１２の上面１２ｂと上下方向に対向する鍔部１３ｂとを有する。蓋基板１１の外周側面１１ｃには、皿頭ネジ１６を固定するための複数のネジ穴１１ｄが形成されている。筒状部１３ａには、複数のネジ穴１１ｄとそれぞれ対向する位置に皿頭ネジ１６を通すための複数の貫通孔１３ａ１が形成されている。【選択図】図２
