To provide a ladder with improved ease of use by improving the ease of repair for instance.SOLUTION: A ladder 1 is mainly made up of vertical members 11a and 11b extending in the vertical direction and horizontal members 21a to 21d extending in the horizontal direction and connecting the vertical members 11a and 11b to each other which are positioned in an adjacent manner. Each of the horizontal members 21a to 21d extends in the horizontal direction and is mainly made up of a core member connected to the vertical members 11a and 11b, and a coating member detachably covering at least a part of the core member. With such a configuration, the performance can be recovered by replacing only the covering material when the horizontal member 21a deteriorates due to use, so that the ease of repair is improved and the usability is improved.SELECTED DRAWING: Figure 1

    【課題】 補修の簡便性を向上させる等して使用勝手が向上したはしごを提供する。【解決手段】 はしご1は、縦方向に延びる縦材11a、11bと、横方向に延び、隣接する縦材11a、11b同士を接続する横材21a〜21dとから主に構成されている。横材21a〜21dの各々は、横方向に延び、縦材11a、11bに接続される芯材と、芯材の少なくとも一部を着脱自在に被覆する被覆材とから主に構成されている。このように構成すると、横材21aが使用により劣化したときに被覆材のみを交換することで性能を回復することができるため、補修の簡便性が向上し、使用勝手が向上する。【選択図】 図1
