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.
