Abstract:
To keep a length between a bolt 5 and a tightening nut 4 constant in order to solve the problem that conventional measures of preventing looseness after tightening bolts and nuts use washers as accessories, which may cause looseness due to vibration, where the looseness is a phenomenon in which the bolts or nuts rotate due to vibration, and the length between the bolts and nuts increases.SOLUTION: A length between a bolt 5 and a tightening nut 4 does not change when the tightening nut 4 is tightened by a combination of a cylindrical pipe 2, the bolt and a reverse screw bolt 1. Consequently, loosening of bolts and nuts after tightening can be prevented.SELECTED DRAWING: Figure 1
