See full text

A ladder includes a pair of protruding portions protruding outwardly on opposite sides in the direction of alignment of the longitudinal bars at the upper end of the longitudinal bars. Structures are provided with a pair of placement support portions spaced apart by a set distance that is longer than the distance between the outer side surfaces of upper end portions of the longitudinal bars in a direction of alignment thereof. The amount of protrusion of the protruding portions is such that the protruding portions overlap in plan view with the placement support portions located at the respective corresponding positions when the ladder is oriented such that a direction of alignment of the upper end portions of the longitudinal bars coincides with the direction of alignment of the placement support portions.
