Claims

[Scope of Claim for Utility Model Registration] A grounding wire extraction sleeve in which a grounding wire extraction path is formed by penetrating in the axial direction of a rubber sleeve body that is fitted around the outer periphery of a power cable, wherein the rubber sleeve body is The inner diameter is uniform, but the outer diameter is smaller in the proximal sleeve part and larger in the distal sleeve part than in the proximal sleeve part, and the outer diameter is formed in the rubber sleeve main body. The ground wire extraction path is provided in the proximal sleeve portion as a groove that is opened along the axial direction on the inner circumference thereof, and in the distal sleeve portion, it is continuous with the groove and is connected to the distal sleeve portion. What is claimed is: 1. A grounding wire draw-out sleeve, characterized in that the sleeve is provided as a hole formed by penetrating in the axial direction through the thickness of the grounding wire.
