Abstract

In a harness for conduction, a knitted fabric that despite having high stretchability and flexibility as well as restorability at the time of repeated elongation, has the characteristics that a change in electrical resistance is zero or suppressed between elongation and non-elongation has never been available. A conductive part knitted using a conductive yarn and an elastic yarn simultaneously, and a non-conductive part knitted using only a non-conductive yarn are provided, in which the conductive part is such that at least the conductive yarn is provided in a zigzag arrangement in a front-back direction in a knitted fabric, and the elastic yarn is provided in an arrangement that generates a tightening force along a surface direction parallel to the front and back surfaces of the knitted fabric to keep the shape of the zigzag arrangement of the conductive yarn, the conductive part includes a constituent path employing a metallic wire as the conductive yarn, and the non-conductive part includes a constituent path employing a synthetic fiber as the non-conductive yarn.

First claim

The invention claimed is:

1. A harness for conduction, comprising:
a conductive part knitted using a conductive yarn and an elastic yarn simultaneously and a non-conductive part knitted using only a non-conductive yarn,
wherein the conductive part is such that at least the conductive yarn is provided in a zigzag arrangement in a front-back direction in a knitted fabric and the elastic yarn is provided in an arrangement that generates a tightening force along a surface direction parallel to front and back surfaces of the knitted fabric to keep a shape of the zigzag arrangement of the conductive yarn,
wherein the conductive part includes a constituent path employing a metallic wire as the conductive yarn, and
wherein the non-conductive part includes a constituent path employing a synthetic fiber as the non-conductive yarn.
