LOCKING NUT

摘要

PURPOSE: A locking nut is provided to prevent loosening due to vibration by comprising elastic compression pieces radially arranged, thereby maintaining stale and strong coupling of a structure. CONSTITUTION: A locking nut comprises a main body(10), a stepped part(30), an outer recess(21), and an inner recess. The main body member has a hexagonal exterior shape in which female thread(1a) is formed in whole. The stepped part is formed on the upper part of the main body into a columnar shape having wide-bottom and narrow-top interior(35). The outer recess and the inner recess are formed to correspond to the boundary between the stepped part and the main body.
