For example, the tapered portion 3a of the pointed bar-shaped portion 3 does not necessarily need to be formed, but if the tapered portion 3a is formed, the tip rod-shaped portion 3 will fit into the connecting portion 4 as tightly as possible. Even if there is a manufacturing error that would not be possible,
There is an advantage that the connection and body fixing of the ground rods 1, 1 can be strongly performed by biting the tapered portion 3a into the connection recess 4.
