The fall prevention device includes a support portion supported by the installation surface, a first restricting portion supported by the support portion, correspondingly disposed above an upper surface of a base portion, and having a first shaft-penetrating portion through which a shaft portion penetrates, and a second restricting portion disposed above the first restricting portion at a bottom-portion-side end portion of the shaft portion. The second restricting portion has a second shaft-penetrating portion through which the shaft portion penetrates. A gap that is smaller than a gap between the first shaft-penetrating portion and the shaft portion is formed between the second shaft-penetrating portion and the end portion of the shaft portion.
