On the other hand, a pair of horizontal rails 15 a and 15 b are arranged on the ceiling 5 a along the rectangular opening 7 in parallel with the horizontal rail 15 c of the floor 6. A suspension member 17 is suspended from the pair of horizontal rails 15 a and 15 b, and the other step plate 13 of the upper staircase and the lower staircase is disposed at the lower end of the pair of suspension members 17. The side ends 13a and 13b are fixed. The upper and lower steps of the step plate 13 are supported at both ends by this and the column 17a.
[0036]
A notch (not shown) is provided at the center in the width direction of the middle landing 13c so as to accommodate the support column 17a in the retracted state.
[0037]
Moreover, if the structure of the kick board and engagement flat plate which concerns on the said modified example is applied to the said lower staircase, positioning of a staircase state and a retracted state can be made easy. Furthermore, in order to stabilize such positioning, it is desirable to apply a similar configuration to the upper staircase, but in this case, the configuration is almost opposite to that of the improved example. That is, the upper end edge of the kick plate as the long piece is fixed to the leading edge of the step plate, and the engaging flat plate as the short piece protruding upward is fixed to the front end edge of the step plate, and the staircase from the retracted state. What is necessary is just to make it the lower end edge of a kick board engage with the upper end edge of the engagement flat plate of the step board of one step lower stage, when pulling out to a state.
