Claims

[Scope of Claim for Utility Model Registration] A tension member extending in the longitudinal direction of the borehole and reaching the tip of the borehole at one end, a tapered part whose outer diameter gradually increases toward the end, and a tapered part at the other end. An anchor bolt having a male thread, and an anchor bolt having a female thread screwed together with the male thread, the anchor having a substantially cylindrical outer shape and an inner diameter gradually decreasing in the axial direction of the cylinder. A permanent ground anchor comprising a fitting part that fits into a tapered part of a bolt, and a connector connecting the other end of the tendon and the anchor bolt, the anchor bolt A permanent ground anchor, wherein the outer surface of the tapered part and the inner surface of the connector have a non-slip part.
