Title:

ANTISTATIC FLEXIBLE TUBE

Document Type and Number:

WIPO Patent Application WO/2020/209352

Kind Code:

A1

Abstract:

The present invention prevents increases in the contact resistance of a conductive layer and a conductive wire associated with the bending of a flexible tube and also prevents damage to and separation of the conductive layer and the conductive wire.　An antistatic flexible tube that is characterized by comprising a tube body that is formed from a flexible soft material, a conductive layer that is provided along an outer circumferential surface of the tube body in the axial direction, a conductive wire that is helically wound along the outer circumferential surface of the tube body and an outer surface of the conductive layer so as to press the outer circumferential surface of the tube body and the outer surface of the conductive layer in the radial direction, and a reinforcing member that is helically provided along the conductive wire so as to protrude from the outer circumferential surface of the tube body and the outer surface of the conductive layer, the conductive wire being sandwiched between the reinforcing member and the outer surface of the conductive layer such that the surface of the conductive wire is pressed onto the outer surface of the conductive layer.
