Claims

[Scope of utility model registration request]

A rod that can be inserted to a predetermined position into a through hole provided in a portion to be tightened of the base body and has a first threaded portion on the tip side, and a second threaded portion that is screwed into the first threaded portion of the rod. a nut member having a threaded portion, which is relatively rotatable around the axis of the rod, and which tightens the tightened portion of the base body by screwing as the nut rotates;
A tightening knob having a cylindrical portion that is movably fitted in the nut member in the axial direction and a lever-like protrusion that projects in the radial direction of the cylindrical portion; On the other hand, in a state in which the tightening knob and the nut member are in a predetermined axial position, the tightening knob and the nut member are engaged with each other at a desired relative position around the axis, and the tightening knob is axially moved by a predetermined amount or more relative to the nut member. 1. A tightening device comprising: detent means that are disengaged from each other in a slid state.
