緩み止め構造。In a bolt fastening body having a nut with a round outer periphery, a number of grooves along the center line are provided on the outer periphery of the nut in the circumferential direction, and the inner diameter is slightly larger than the outer periphery of the nut, and a circumferential groove is provided on one end surface along the center line. A locking sleeve that is divided in multiple directions is fixed to the object to be fastened, and the inside and outside of this sleeve are made of metals with different coefficients of thermal expansion so that the sleeve deforms inside the sleeve in the operating temperature environment of the bolt fastened object. A nut locking structure characterized by having a bimetallic structure.
