With this configuration, the cross-sectional shape of the buried pipe or the column on which the convex portion is formed becomes substantially the same shape over the entire length of the insertion support portion. For example, such protrusions are easily formed by extrusion molding. Therefore, when implementing the support structure of a pillar according to the present invention, it is possible to minimize an increase in manufacturing costs and man-hours.

According to a third aspect of the present invention, when the buried pipe has a substantially cylindrical cross section, the buried pipe extends along an axial direction of the buried pipe on an outer peripheral surface of the buried pipe. At least one flange protruding in the radial direction of the buried pipe was formed.

According to this structure, even if the buried pipe has a substantially cylindrical cross section, the buried pipe is prevented from rotating underground by the flange formed on the outer peripheral surface of the buried pipe.
For example, when the present invention is applied to a tennis post, if the tennis post and the buried pipe are provided with a rotation stopper, the rotation of the tennis post is prevented, and the net tensioning operation is performed smoothly.

In the invention according to claim 4, at least one fitting portion for fitting between the adjacent convex portions is formed on the other surface of the inner peripheral surface of the buried pipe and the outer peripheral surface of the column.

[0013] According to this structure, the fitting portion formed on the other surface of the inner peripheral surface of the buried pipe and the outer peripheral surface of the column is connected to the adjacent convex portion formed on one surface of the inner peripheral surface of the buried pipe and the outer peripheral surface of the column. The rotation of the buried pipe and the support column is prevented from being relatively engaged. Therefore, it is not necessary to provide a rotation stopper for fixing the buried pipe and the column relatively to the outside, and the rotation of the column is prevented while preventing the appearance of the column from being damaged and preventing the stopper from being damaged during construction.
