In this case, the horizontal guide rails 2p and 2q become the sealing base members Bd and Be, and also serve as both. Therefore, the upper surfaces of the horizontal guide rails 2p and 2q become the sealing surfaces Ed and Ee. Thereby, the shielding property is further improved.

Next, the sealing structure of the gap Gc between the case support frame 3y and the storage case Cy will be described.
This will be described with reference to FIGS. In this case, the width of the storage case Cy gradually decreases toward the lower side, and a gap Gc is generated. Therefore, a sealing portion 50 that shields the gap Gc is attached to the case support frame 3y. Note that the same sealing structure is adopted also on the case support frame 3x side.

First, four strip-shaped sealing plate portions 5 are provided on the inner edge of the case support frame 3y.

The mounting plate portion 58 is fixed to a predetermined position on the lower surface of the sealing plate body 54w by screws 62. As shown in FIG. 5, the tip end 54wf of the sealing plate body 54w is curved upward to form a semicircular cross section, and a cutout 63 for accommodating the roller 61 is formed at a position where the roller 61 exists. This allows
When the roller 61 contacts the side surface Cys of the storage case Cy, the tip end 54wf of the sealing plate body 54w approaches the side surface Cys.

Thus, by screwing the brackets 56m and 56n to the case supporting frame 3y, one side of the sealing plate 54 is connected to the case supporting frame 3y.
The other side is always in contact with the side surface Cys of the storage case Cy by the biasing action of the spring 59. As a result, the gap Gc between the case support frame 3y and the storage case Cy is shielded by the sealing plate portion 54, thereby preventing falling of an object or the like under the floor and preventing blowing of wind from under the floor. Thus, the displacement of the storage case Cy is prevented. In this case, since the gap Gc is narrowed by the lowering of the storage case Cy, the sealing plate portion 54 is pivotally displaced downward as shown in FIG. 2, while the gap Gc is widened by the rise of the storage case Cy. The plate portion 54 is pivotally displaced to a substantially horizontal position as shown in FIG. In addition,
6, the case supporting frame 3y shows a state in which the sealing plate portions 54 are displaced downward, and the case supporting frame 3y shows a state in which the sealing plate portions 54 are displaced upward.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The configuration, shape, and the like of the details can be arbitrarily changed without departing from the gist of the present invention.
