となることを確認した。As a result of the test after the previous application, the inventor has found that the tapered portion 8 has a truncated cone shape and the engaging rod 6 has a different sectional shape from the truncated cone, for example, a hexagonal rod. It has been found that a shearing stress concentrates on this step portion and cuts from this portion because a right-angled step portion having a narrow cross-section and abruptly changing occurs at the boundary between the taper portion 8 and the engaging rod 6. Therefore, the slanted surface and the flat surface of the engaging rods 5 and 6 are engaged with the hexagonal hole a ′ of the head of the hexagon socket head bolt a through the tapered portions 7 and 8 of the polygonal frustum shape whose diameter is gradually reduced. When they are continuously installed in a state, as shown in FIGS. 5 and 6, there is no right-angled step at the boundary between the slope and the flat surface, and the slope and the flat surface are continuous, so that shear stress does not concentrate at the boundary and the engagement occurs. It was confirmed that the rods 5 and 6 were a wrench for a bolt with a polygonal hole without breaking.
