Consolidated. In addition, the number of the support pipes 2 erected from the connecting portion pipe 6 or the connecting portion main body 7 is determined according to the size of the tree and the root pot.

The sectional shapes of the support shaft 1 and the support tube 2 are not particularly limited as long as the support shaft 1 and the support tube 2 can be inserted.

Further, the support shaft 1 may be a pipe, and the support shaft 1 may be externally fitted to the support tube 2. When the support shaft 1 is externally fitted to the support tube 2, the support tube 2 need not be a pipe. The support shaft 1 and the support tube 2 are provided with a fixing means such as a structure in which a bolt is screwed from the outside so that the support shaft 1 and the support tube 2 can be fixed at a required position.

The connecting portion 8 connects the support tube 2 and the pedestal 4. The connecting portion pipe 6 externally fits a part of the pedestal arm 5, and two connecting portion pipes 6 facing each other. It is desirable to have a structure including the connecting portion main body 7 to be erected. In this case, if the pedestal 4 has an arm arranged in a cross-girder shape, the connecting portion pipe 6 slides the pedestal arm 5 or the like, so that the pedestal arm according to the size of the root mortar 9.
