<p>PROBLEM TO BE SOLVED: To provide an installing aid which allows the state of attachment to be checked through feeling or hearing during operation, and wire branching hardware to be attached to a supporting wire with reliability, even if external force is exerted on a support plate. SOLUTION: A through-hole is formed in proximity to the base of a bend and a supporting wire enclosing portion to be fitted into recesses 24 is formed at the tip of a V-shaped plate spring 10. A supporting wire lead-in port 38 is set that the width of the supporting wire lead-in port is smaller than of the supporting wire 26 is formed in such a manner, that the supporting wire lead-in port is continuously extended from the supporting wire enclosing portion. As a result of constituting the V-shaped plate spring 10 in such a manner as mentioned above, resistance is increased or decreased when the supporting wire 26 goes through the supporting wire let-in port 38, so that the state of attachment can be checked through touching. It can be also checked through the production of attaching noise due to contact between the supporting wire 26 and the supporting wire enclosing portion 36. Further, since the supporting wire enclosing portion 36 couples the recessed portions 24 together, the relative position between support plates 18 is not varied, and wire branching hardware 12 can be attached to the supporting wire 26 reliability.</p> |
