<p>PROBLEM TO BE SOLVED: To provide an insulation operation rod which is capable of varying an angle formed from a rod body constituent member and a rod constituent member over a range from right angle to obtuse angle and also facilitates work for varying the angle.SOLUTION: A rod body 2 that an insulation operation rod 1 comprises, includes a rod body constituent member 21, a rod body constituent member 22, and a concatenation mechanism 8. The concatenation mechanism 8 is formed from a meshing structure 10, a meshing structure 11, and an elastic mechanism 12. The meshing structure 10 includes a circumferential surface 101a in an arcuate shape, and a protrusion is radially disposed on the circumferential surface 101a. The meshing structure 11 includes a circumferential surface 111 in an arcuate shape which can be brought into contact with the circumferential surface 101a of the meshing structure 10, and a recess is radially disposed on the circumferential surface 111 so as to be meshed with the protrusion of the meshing structure 10. By displacing positions where the protrusion of the meshing structure 10 and the recess of the meshing structure 11 are meshed, an angle formed from the rod body constituent member 21 and the rod body constituent member 22 can be varied over the range from right angle to obtuse angle.</p> |
