Abstract
A climbing apparatus body is supported by a main frame rotatably about a rotational shaft at one end. The climbing apparatus body is capable of taking an in-use posture in which the climbing apparatus body is inclined so that the other end is located below the one end and a folded posture in which the climbing apparatus body stands so that the other end is directed upward. A handrail is supported by the main frame. A pair of right and left banisters is attached to the climbing apparatus body and includes a portion extending toward the handrail relative to the position (perpendicular line) of the rotational shaft in the direction from the other end to the one end in the in-use posture in a side view of the climbing apparatus body.
