PROBLEM TO BE SOLVED: To prevent a plate from rotating/shifting by engaging and fixing the plate to an anchor, and to surely fix the plate, by adopting such a structure that a nail being the axis core of the anchor is hammered, in order to widen the width of the axis head when fixing it.;SOLUTION: In a permanent installing structure constituted of the plate 1 for expressing positional information and the anchor 3 for fixing the plate to the ground, engaging sections are formed in the plate 1 and the anchor 3, respectively, and engaged with each other, thereby preventing the plate from rotating about the anchor. The anchor 3 comprises a head section 7, contacting with the plate and a shaft 8 which extends from the head section and is fixed in the ground, and the nail 2 is hammered in the axis core from the head section. When the nail 2 is hammered in toward the head of the shaft, the top of the nail 2 is butt into the head of the shaft, the width of axis head is widened, and the anchor is fixed in the ground by the widened section.;COPYRIGHT: (C)2007,JPO&INPIT
