<p>PURPOSE: To improve a workability by a method wherein a slit is formed at a substantially right angle to the same side from a crossing point between one side of a projecting piece formed at one end of a side plate and one end of the side plate, a flange is bent and formed along a bending line connecting the extremity end of the slit and the other side of the projecting piece and one end of the side plate and a threaded hole is arranged at the central part of the flange. CONSTITUTION: A slit 3f is formed at either a right side or a left side of a flange 3d, the flange 3d is bent along a bending line 3g connecting the extremity end of the slit 3f with one end of a side plate 3c in a substantial 90 deg. and it is formed by a slant of a substantial L-shape. With such an arrangement as above, a head part of the screw 3i and a head part of the side plate 3c can be set to the substantially same height, the head part of the screw 3i is not projected out of the end part of the side plate 3c and when it is transported or stored, it can be easily handled. In addition, an earth terminal 3h is threadably fitted to a threaded hole 3e arranged at a flange 3d with the screw 3i in an inclination angle, thereby the extremity end of the screw 3i does not approach a U-shaped pipe 3b and the U-shaped pipe 3b is not damaged.</p> |
