The tapered shape or the inclined surface serves as a pressure contact portion that serves as a force for sandwiching the mounting member, and the tapered shape or the inclined surface is inclined toward the direction sandwiching the mounting member.

Further, the taper shape and the inclined surface of the lower portion are made smaller in diameter downward so that the ring body or the body can be easily contracted so as to fit into the mounting hole.

Further, if the distance between the separated portions of the ring is increased, the diameter of the ring is increased, and conversely, the compression can be performed until the diameter of the ring is decreased, and the change in the diameter can be increased. This makes it easier to fasten the members.

Although all the ring bodies described so far have been described in the case where the cutout portion is provided in a part of the ring, the present invention does not rely on providing the cutout portion in a part of the ring. It is also possible to provide a thin portion at least at one place.

Instead of the separating portion, the separating portion of the ring may be formed as a thin coupling portion so that the thin coupling portion is broken.

If the thin coupling portion of the ring is bent so as to have elasticity so that the portion expands and contracts due to compression, the same effect as providing the cut portion on the ring can be obtained. The body is what you get.
