Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a screw point on which strength of a connecting part with a rod is enhanced. SOLUTION: This screw point 3 is installed on the tip of a rod 2 having a prescribed length, and is intruded underground integrally with the rod 2. In that case, a female screw 2a is formed on the tip of the rod 2, and a male screw member 4 such as stud bolt is screw fitted to this female screw 2. A fitting hole 3b to which the tip of the rod 2 can be fitted and a female screw 3c to which the other end of the male screw member 4 can be screw-fitted, are formed in the screw point 3, and in a condition where the tip of the rod 2 is fitted to the fitting hole 3b, the male screw member 4 is screw-fitted to the female screw 3c.
