を嵌合定着してなるロツクボルト装置。 A cylinder is formed by bending a thin steel plate and inserting a narrow piece at one end into a hole at the other end, and making a U-shaped cut in the narrow piece and pushing out the part inside the cut. A locking piece is formed on the outside of the other end of the hole to form a tongue piece whose tip side projects outwardly, and a locking piece is provided on the outside of the other end edge of the hole to form several tongue pieces that protrude inwardly at the vertically intermediate portion of the cylinder body. Dowels are provided at appropriate intervals, and several legs protrude diagonally downward and outward from the lower periphery to form temporary fixing fittings.
A lock bolt device is formed by fitting and fixing the cylindrical body of the above-mentioned temporary fitting into an appropriate position of a lock bolt.
