[0002]

2. Description of the Related Art A fence is connected to a cylinder of this kind by connecting the fence in two directions from the cylinder so as to form a curved surface in series or at a predetermined angle with respect to the cylinder. , For example, a cylinder, a fence arranged in two directions from the cylinder, and a curved band projecting in the cylinder direction from each of the fences arranged on the furring edge of the fence by bolt nuts through through holes. The fences in these two directions are connected to the cylinder by fastening and fixing to the cylinder, and the bending band has a length of 1/3 to 1/2 of the circular arc of the cylinder and the same diameter as the outer diameter of the cylinder. It is designed to be slidable on the outer peripheral surface.

[0003]
