Claim 5:
6. The locking bolt according to claim 1
further comprising a rotation-stopping feature such that a small protrusion which is distinct from the eccentric columnar portion is provided at the cutting plane of the first bolt or the second bolt, and a semicircular groove which is concentric with respect to the eccentric cylindrical portion but which is distinct from the eccentric cylindrical portion is provided at the opposite cutting plane, and such that after these are mated to the point where a state is reached in which the mutual cutting planes of the first bolt and the second bolt come in contact, rotation of only the second bolt causes mutual engagement of the small protrusion and an end of the semicircular groove to occur at a place where the pitches and the central axes of the external threaded portions of the two are aligned, preventing the second bolt from rotating further.
