The fastening reaction body 410b includes a fastening reaction body elastic support 411b, a fastening reaction body elastic connecting part 413b, and a fastening reaction body elastic notch 415b. The fastening reaction body elastic support 411b includes a drain bolt part. It is arranged on the 200 side. More specifically, the fastening reaction body elastic support 411b is disposed on the fastening body 310 side disposed at the end of the bolt body 210 of the drain bolt part 200, and the fastening reaction body elastic support 411b is fastening reaction body It is connected to the fastening body 310 through the elastic connector 413b. That is, the fastening reaction body elastic connecting portion 413b is disposed in the longitudinal direction of the bolt body 210, and one end of the fastening reaction body elastic connecting portion 413b is disposed at the end of the bolt body 210 of the drain bolt portion 200. The other end of the fastening reaction body elastic connecting portion 413b is connected to the fastening reaction body elastic support 411b. The other end of the fastening reaction body elastic support 411b is formed at the free end and the fastening reaction body elastic support 411b is disposed in the circumferential direction of the bolt body 210. The fastening body main portion 311 and the fastening reaction body elastic support part 411b and the fastening reaction body elastic connecting portion 413b have a '-' shape.

Through such a configuration, the fastening reaction body elastic support part 411b is in contact with the fastening reaction body corresponding part 420b disposed on the inner surface of the base through hole 110 to form a predetermined elastic support structure.

In the present embodiment, the fastening reaction force elastic notch 415b is disposed on the side of the fastening reaction force elastic connecting part 413b, which is an example of the present invention. However, it is preferable to take a configuration in that it can prevent damage due to interference between components and form a smooth elastic support structure even by repeated pressing through the fastening reaction body elastic notch 415b. .

20 to 22 are schematic partial cutaway perspective views illustrating the operation of the drain bolt unit 10b having the fastening reaction body 410b of the present invention. First, as shown in FIG. 20, the drain bolt part 200 enters and is received toward the base through hole 110 of the drain base 100, where the fastening reaction body elastic support 411b is fastening reaction body corresponding part. Even in contact with 420b, a predetermined pressing force may be continuously provided to form a fastening state of the drain fastening part 300. Then, as shown in FIG. 21, in the state where the pressing force P is provided, the bolt knob 220 is adjusted around the line OO to achieve an axial rotation, and through this process, the drain fastening part 300 is fastened to a predetermined level. Form a state. Then, when the predetermined pressing force P by the user is removed, the predetermined elastic reaction force is provided through the elastic restoring force accumulated during elastic deformation of the fastening reaction body elastic support 411b and the fastening reaction body elastic connecting portion 413b. Through this elastic reaction force, the engagement state between the fastening body and the fastening body counterpart is secured, and the sealing structure between the drain sealer 500 and the inner surface of the base through hole 110 disposed on the outer circumference of the bolt body 210 is further increased. By consolidation, oil leakage through the gap between them can be more easily prevented.

The above embodiments are examples for describing the present invention, and the present invention is not limited thereto, and various modifications are possible.
