Also, at the time of construction, if there is an obstacle i such as a wire pipe or a large stone displaced from a predetermined arrangement position at a position interfering with the horizontal rod c connecting each vertical rod b, the horizontal rod c is shifted. Because of this, it was necessary to deal with obstacles by rewiring pipes and cutting stones, and the construction work was troublesome. Further, the conventional fixing anchor a has a large number of welded portions because all the joining of the vertical rod b and the horizontal rod c is performed by welding.
There is a problem that the manufacturing efficiency is low and the material of the welding portion is thinned due to high heat at the time of welding, so that the strength of the fixing anchor a is reduced.

An object of the present invention is to provide an anchor for fixing a streetlight pole which can solve the problems of the conventional structure.
