2. Description of the Related Art For example, a fence is sometimes used at the border of an airport site or on the course side of a racetrack. FIG. 5 is a side view of a conventional fence provided with a height adjusting device, in which a fence 1 is a cylindrical column 2 erected on the ground G, and is attached to an upper end of the column 2 so as to extend in the longitudinal direction of the column. It comprises an angle member 3 extending at a predetermined angle with respect to the angle member 3 and a cap 4 fixed to the tip of the angle member 3. A plurality of pillars 2 are erected on the ground G in a required direction at an appropriate interval, and a cap 4 is attached so as to connect the tips of the angle members 3 of the pillars 2.

[0003] In general, when the pillar 2 is buried in the ground G with a concrete anchor, the height of the fence hardly changes over time unless an earthquake or the like occurs. However, especially at airports and racetracks, the columns 2 are often erected directly on the ground G without using concrete anchors so as not to adversely affect the drainage of the surrounding farmland or the course. In this case, some struts 2 may sink or be lifted off the ground G due to the impact at the time of landing of the aircraft or the vibration at the time of horse running on the riding ground. It is arranged in a wavy manner, the appearance is deteriorated, and the cap 4 is in a state of being distorted, and the fence may be cut and disassembled by a slight external force, which is dangerous. Under such circumstances, the height of the fence needs to be adjusted.

[0004] The conventional fence height adjusting device is configured as follows. That is, a hollow portion 5 opening at the upper end surface is provided in the support column 2, an insertion portion 6 of the angle member 3 is inserted into the hollow portion, an adjustment bolt 7 is screwed into a side surface of the support column 2, and a tip of the bolt is inserted into the insertion portion 6. It was structured to be pressed against the outside surface.

[0005] If the column 2 is settled or lifted, the bolt 7 is loosened to make the angle member 3 free from the column 2, and the angle member 3 is removed from the support member 4 so as to eliminate the ripple. The position with respect to the support 2 is adjusted, and the bolt 7 is tightened at that position to fix the angle member 3 to the support 2.

[0006]

In order to adjust the height of the fence using the above-described conventional height adjustment device for the fence, at least two workers are required. That is, one worker loosens the bolts 7 of each column 2 and holds the cap 4 in a horizontal state, while another worker monitors the entire fence from a position a little away, If necessary, the user is instructed to correct the holding height so that the cap 4 is held completely horizontal. Then, the bolt 7 is tightened by another worker who has confirmed that the cap 4 is held horizontally, and the angle member 3 is fixed at the corrected height.

[0007] In such a conventional work for adjusting the height of the fence, at least two workers are required, the work of holding a heavy casket is not easy, and the work shared by the workers is complicated. There is a problem that the adjustment work takes a long time. The present invention has been made in view of the current state of the above-mentioned conventional fence height adjustment work, and its purpose is to provide a height adjustment device that allows one worker to easily adjust the height of the fence. To provide fences with
