の緩み止め構造。For drum tightening, the nut into which the bolt is screwed has a shape in which a screw hole is drilled in a columnar body in a direction perpendicular to the axial direction of the nut, and a hole is placed on the outside of this nut at a position that matches the screw hole. For the tightening, a synthetic resin elastic tube having a bolt fitting hole with a smaller diameter than the outer diameter of the threaded portion of the bolt is tightly fitted, and the bolt is tightened on the inner peripheral surface of the bolt fitting hole of this elastic tube. The drum fastener is characterized by retaining the threaded part of the bolt and has a structure that prevents the bolt from loosening.
