た。However, the conventional perforated bed has various problems as described below. First,
An open-air floor made of expanded metal is dangerous because burrs may occur, and when using a carrier on the floor,
There was a problem that the transport vehicle lacked smoothness and the wheels were easily damaged. Next, the perforated bed made of punching metal has a problem that it is difficult to process because it is likely to be distorted and strength design is also difficult, so that the opening area cannot be sufficiently secured. Further, the open-hole floor made of the grating metal described in the above publication has a high processing cost, and when using a carrier on the floor, lacks smoothness in traveling of the carrier,
In addition, the wheels are easily damaged, and the distance between the master bars (floor materials) is limited, so that the distance cannot be widened. Furthermore, these conventional perforated floors have a problem that the person on the floor feels uncomfortable because the person on the floor can see through the floor.

It is possible to make it possible to keep the wheels from being damaged, the floor materials can be widely spaced, and it is possible to secure the required opening area by communicating with the upper and lower surfaces, which is legal as a disaster prevention structure, and below the open floor. It is to provide a perforated bed where the upper part of the perforated bed cannot be seen through from any angle.

When used, it can be smoothly moved, its wheels are not damaged, and it is durable and economical. In addition, it is possible to widen the space between the floor materials. It is also safe for people to pass. Further, the open-hole floor of the present invention is suitable as a disaster prevention structure because it can communicate with the upper and lower surfaces and secure a required opening area.
Furthermore, since the upper part of the open floor cannot be seen from any angle below the open bed, when a person who is under the floor looks up, the person on the floor is seen, which is especially unpleasant for women. It doesn't feel like it.
