PROBLEM TO BE SOLVED: To accelerate and facilitate fitting work so as to solve the problem that a fitting means takes time and costs. SOLUTION: Concerning a receiving metal fitting 1 the external shape of which is U-shaped and which consists of one side surface part and peripheral side surface part 3 to be in a closed state and the other side surface part and upper side surface part 5 to be in an open state, projection pawls 6 are provided inward at a position closer to the upper side surface part from both sides of the center of the diameter part of the periphery side surface part, and the end parts of a prescribed pole 7 are pressurized and fixed strongly toward the other side surface part and upper side surface part to be in the open state of the receiving metal fitting constituted like this.
