PROBLEM TO BE SOLVED: To provide a stepladder capable of making a worker hardly stand or sit on a top board in use and capable of preventing the worker from falling from the top board.SOLUTION: In a stepladder 1, two ladder frames 5, which each have a plurality of rungs 3 arranged between two studs 2 and which each have a top board 4 attached to an upper end between the studs 2, are provided, and upper ends of the studs 2 of the two ladder frames 5 are pivotally attached by a hinge 6. An arc-shaped cross-section cushion member 7 is attached onto the top board 4 of one ladder frames 5 of the two ladder frames 5 in such a manner that an outer peripheral surface is directed upward.
【課題】使用時に作業者が天板上に立ったり腰掛けたりしにくくでき、作業者が天板から落下することを防止し得る脚立を提供する。【解決手段】二本の脚柱２間に複数の踏桟３が配設され且つ該脚柱２間上端に天板４が取り付けられた梯子枠５を二個備え、該二個の梯子枠５の脚柱２上端を蝶番６にて枢着した脚立１において、二個の梯子枠５のうち一方の梯子枠５の天板４上に、断面円弧形状のクッション部材７を外周面が上に向くよう取り付ける。【選択図】図１
