A plurality of electric wires, which are supplied to a part of the header from a twist part through the electric wire passage hole of the rotary body, are connected to the pair of press-connecting bodies each having a press-contact claw and a pair of press-contacting bodies for starting and ending purposes. On either side of the body, the electric wires are connected by pressure contact to the connectors set in advance on the fixing jig, and the electric wires are twisted together to form a twisted wire by the rotation of the rotating body. The gist of the invention is to manufacture a wire harness by repeatedly moving the wiring mechanism in accordance with the position of the fixing jig.

For Kusaku The effect will be explained below.

The tips of the plurality of electric wires that form a set, which are supplied through the plurality of electric wire through holes provided in the cylindrical rotating body of the twisting part, are held by the clamping means and simultaneously cut by the cutting means to form the starting side connection end. . Next, the start-side connection ends are respectively press-connected to connectors set in advance on a fixing jig of the jig board using a start press-contact body that is a part of the header. Next, each electric wire whose portion located between the lead-out side end of the rotating body and the connector is made to have a predetermined length by the movement of the wiring mechanism, The portion located in between is twisted by the rotation of the rotating body, and a twisted line is formed at this portion. The twisted wire is held at its twisted end by a clamping means of a part of the header moved onto the corresponding connector, and at the same time is cut by a cutting means to form an end-side connection end.

Then, this end-side connection end is press-connected to the connector by the end press-connecting body. Thereafter, the start-side connection end formed as a pair with the end-side connection end by the above-described cutting becomes the start-side connection end, and the same operation is repeated.
