にするものである。(Prior art) To fix a permanent anchor in a borehole, the anchor is placed in the borehole, and then a grout hardening material is injected into the borehole to adhere to the sheath of the anchor. If the core rots in the drilled hole due to its own weight, there will be no gap between the outer circumferential surface of the sheath and the drilled hole wall, and the hardening material will not be able to circulate between the two, and the adhesion force in this area will be reduced. It will drop. (FIG. 9) In order to solve such problems, an invention as shown in FIG. 10 has been developed. That is, an elastically deformable leaf spring-like overhang made of IR is attached to the outer periphery of the sheath a at an appropriate distance in the circumferential direction, and the anchor is cut so that the overhang is protruded into the drilled hole C. It is to be located at the center of hole C.
