To provide a lightweight and easily adjustable support by applying the constitution that a wear plate is provided at the lower end of an expansible support having a threaded part, the wear plate is fixed to the ground for supporting a fence post and the inclination of the post due to a secular change or the like is adjusted via the expansion or contraction of the support.

A post body 10 is driven into the ground and fixed. At the same time, supports 1 connected to each other via a connecting ring (tube joint) are connected to the post body 10 at an angle of approximately 45 degrees. In this case, a holding plate (support wear plate) 7 is fixed to the lower end of the supports 1 and fixed to the ground. In addition, the upper ends of the supports 1 are fixed to the post body with screws. Then, a wire fence 11 is attached to the post body 10 and tension is applied to a wire, thereby completing a fence. When the inclination of the post body 10 is finely adjusted, the connecting ring is turned for expanding or contracting the supports 1 and making adjustment in the case of the non-inclination of a corner post or the like, due to the change of soil bearing capacity, a temperature change or the like. According to this construction, the supports 1 can be made compact and lightweight, and mounting or transportation efficiency can be improved.
