  By being configured in this manner, as indicated by an arrow α in FIG. 6, the rising portion 15 of the lower floor 8 is not visible from above the upper floor 7, so standing on the balcony 2 and viewing the outdoor direction. In this case, there is no rising portion 15, and it seems that the handrail surface material 10 is rising as it is from the outdoor edge of the upper floor 7. Moreover, since the handrail portion 27 of the handrail face material 10 is arranged so that the horizontal receiving material 30 is also located at a position lower than the upper surface of the upper floor 7 of the double floor portion 9, from the outdoor edge of the upper floor 7 Since the glass face material 26 seems to stand up directly, there is nothing that blocks the field of view between the outside and the outside, and a sense of unity with the outside can be created. And the balcony 2 which is a floor structure with a handrail of this embodiment WHEREIN: The upper surface of the upper floor 7, the floor surface 5a of the second-floor room 5 of the house 1, and the lower rail 6 of the sweep window 4 were formed substantially flush. Since it is a flat balcony, there is nothing to block the line of sight between the living room 5 on the second floor and the outside, and it is possible to create a sense of unity from the inside to the outside.

  Further, since the rising portion 15 of the lower floor 8 is disposed below the upper floor 7, the rising portion 15 is not provided on the upper floor 7, so that the rising portion 15 is on the upper floor 7. Compared with the case where it is provided, the range indicated by β in FIG. 5 can be used effectively. Therefore, the area where the upper floor 7 can be effectively used can be increased, and the area of the balcony 2 can be increased.

  As indicated by an arrow γ in FIG. 5, a gap is left between the handrail surface material 10 and the double floor 9, and the gap is covered with the grating lid 33. The ventilation can be ensured even if the handrail portion 27 is the glass face material 26. In particular, since the lower part of the handrail surface material 10 is composed of the lattice surface material 25, it is possible to introduce the wind into the balcony 2 on the indoor side of the handrail surface material 10 through the lattice surface material 25 and further through the gap. The ventilation performance can be improved. Further, since the grating lid 33 is provided, falling objects can be prevented. For example, the drainage drain (not shown) provided on the drainage path of the lower floor 8 is clogged, or the rain exceeds the drainage capacity of the drainage path. For example, when water accumulates on the lower floor 8, the accumulated water can overflow through the gap between the handrail surface material 10 and the double floor portion 9. Can be prevented from staying.

  Furthermore, as shown in FIG. 6, the lattice surface material 25 at the lower part of the handrail surface material 10 has an effect of reducing solar radiation on the first floor because the lower end thereof hangs downward from the eaves ceiling 19. And since it is formed with the lattice face material 25, ventilation is not interrupted.
