Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a floor panel support,
Related to a structure including a tubular material as a constituent element, in particular, a tool is used to rotate the tubular material or fix the tubular material so that the tubular material does not rotate together with other members. It concerns structures that need to be retained.

[0002]

2. Description of the Related Art A tubular member having a circular cross section is used as a normal spanner,
You cannot hook a tool such as a wrench. For this reason,
Conventionally, when a tubular material having a circular cross section is screwed into a male screw material, the tubular material is prevented from rotating or the tubular material from rotating together with other members. When it is necessary to fix and hold the above, it is not possible to do these things with a tool such as an ordinary spanner and wrench, and it is necessary to use a special tool.

[0003]

However, it is inconvenient that only special tools can be used as described above.
Further, in order to make it possible to use tools such as ordinary spanners and wrenches, it has been attempted to process a portion having a non-circular cross section for fitting the tool into the tubular material itself. There has been a problem in that the cost is increased when processing the portion having a non-circular cross section in the material itself.

The present invention has been made in view of the above circumstances, and an object of the present invention is to rotate a tubular member using a tool such as an ordinary spanner or a wrench, or to replace the tubular member with another. It is an object of the present invention to provide a structure including a tubular material, which can hold the tubular material in a fixed manner so as not to rotate together with the member and can be manufactured at low cost.

[0005]

A structure including a tubular member according to the present invention comprises a tubular member and a tubular member which is crimped onto the tubular member and fixed to the tubular member. And a tool fitting material having a non-circular shape into which a tool is fitted to prevent the rotation of the tubular material.

[0006]

In the present invention, by fitting a tool such as a wrench or a wrench to a non-circular tool fitting material, the tubular material can be rotated by these tools, or the tubular material together with other members. The tubular member can be fixedly held so as not to rotate.

Further, since it is only necessary to caulk the tool fitting material with the tubular material and it is not necessary to process the portion having a non-circular cross section into the tubular material itself, the cost can be reduced (particularly,
If the tool fitting material is caulked together with other members to be fixed to the tubular material, the cost increase by providing the tool fitting material is minimized).

[0008]
