A plurality of pillars of the guardrail are fixed to the upper portion of the elevator car. The plurality of sliding columns are slidably engaged with the plurality of pillars, respectively, and can protrude above the upper portions of the plurality of pillars. The fence part is fixed on the plurality of sliding columns. The first switch part and the second switch part cannot be turned on by interfering with one of the plurality of sliding columns, i.e., a switch sliding column. In an expanded state in which the plurality of slide columns extend from the upper portions of the plurality of support columns, the first switch portion interferes with the switch slide column, and the second switch portion avoids interference with the switch slide column.

    扶栏的多个支柱固定于电梯轿厢的上部。多个滑动柱分别以能够滑动的方式与多个支柱卡合,并且能够向比多个支柱的上部靠上方的位置突出。栏部固定于多个滑动柱。第一开关部及第二开关部通过与多个滑动柱中的一个即开关用滑动柱干涉而变得无法接通。在多个滑动柱从多个支柱的上部伸出的扩张状态下,第一开关部与开关用滑动柱干涉,第二开关部避免与开关用滑动柱的干涉。
