Claims

[Scope of utility model registration request]

The proximal end of the first bar having a battledore at its tip is inserted into one end of the turnbuckle in a manner that prevents it from coming out and is held slidably and rotatably, and the base end of the first bar having a battledore at its tip A male threaded portion is formed at the base end, a tightening nut is screwed into the male threaded portion, and a receiving nut having a hole through which the male threaded portion of the second bar is inserted is fixed to the other end of the turnbuckle. A guide groove communicating with the insertion hole is formed at at least one location in the circumferential direction of the inner peripheral surface of the insertion hole of the receiving nut, and a protrusion that fits into the guide groove is formed on one end surface of the tightening nut. and a cylindrical member that can be inserted into the insertion hole by aligning the protrusion with the guide groove, and a cylindrical member that can be inserted into the insertion hole by a predetermined amount in the inner part of the guide groove. In this case, the brace material is formed with a partial circumferential groove that allows the tightening nut to rotate by a predetermined amount in one direction, and a contact portion that comes into contact with the protrusion and restricts the rotation.
