Claim 14:
15. A locking bolt comprising, in such form as if a single bolt had been cut into two at a cutting plane perpendicularly with respect to an axis thereof at a location midway along the axis thereof, a first bolt having a bolt head and a second bolt having a threaded tip, wherein the locking bolt is such that:
the first bolt and the second bolt respectively have, at the outside circumference of the bolt shaft of each of the bolts, male threads that threadedly engage with a single bolt hole;
at the first bolt, an eccentric columnar portion which is smaller in diameter than the diameter of a shaft of the first bolt is provided at the cutting plane between it and the second bolt in such fashion as to protrude outward in the axial direction in eccentric fashion with respect to a direction perpendicular to the central axis of the first bolt, and a side face protrusion is formed at a portion of an outside circumferential side face of the eccentric columnar portion in such fashion as to protrude outward in a radial direction;
at the second bolt, an eccentric cylindrical portion which is a cylindrical hole that is smaller in diameter than the diameter of a shaft of the second bolt and that mates with the eccentric columnar portion provided at the first bolt is formed at the cutting plane of the second bolt in eccentric fashion with respect to a direction perpendicular to the central axis of the second bolt, an axial groove being formed in a direction parallel to the central axis and a radial groove being formed in a direction perpendicular to the central axis at an inside circumferential side face thereof;
after the side face protrusion of the eccentric columnar portion and the axial groove of the eccentric cylindrical portion are aligned and the eccentric columnar portion provided at the first bolt is captured within the eccentric cylindrical portion provided at the second bolt to the point where the cutting planes come in contact in mutually opposed fashion, causing movement of the side face protrusion of the eccentric columnar portion along the radial groove of the eccentric cylindrical portion until an end of the radial groove is reached as a result of rotation of the first bolt results in a constitution in which pitches and central axes of external threaded portions of the two are aligned; and
the second bolt is provided with a recess for rotational actuation.
