PURPOSE:To eliminate wasteful use of an electric wire by providing arms in the number in. compliance with the number of branch lines, stretching the arms in the direction of branching, securing the base end of each arm to the top of the base part with a fixing mechanism, and thereby enabling diverging of a number of branches even in a restricted space. CONSTITUTION:A fixing mechanism for an arm 50 is formed from ring parts 53, a male threaded part 39, and a nut 60. When a wire laying jig 30 is to be erected, the ring parts 53 at the base ends of the arms 50 are fitted one after another on the male threaded part, 39 at the top of a column 33 and are stacked. The number of arms 50 is determined in compliance with the number of divergences of branch lines, and when a certain required number of arms 50 are set, the direction of each arm 50 is adjusted about a fulcrum which is the part 39 constituting the fixing mechanism, and a nut 60 is screwed onto the part 39 and fastened. As a result, the wire jig 30 is accomplished. Therein the direction of each arm 50 is adjusted in accordance with the branch line to be diverged according to necessily. This enables a number of divergences in a restricted area, and it is no more needed to set the branch length larger because the jig 30 can not be erected, which allows eliminating wasteful use of the electric wire. |
