Claims

[Scope of utility model registration request]

said first and second members interposed between said first member and a second member screwed to said first member;
The insulating bushing electrically insulates the second member, the insulating bushing having a plate-like part and a cylindrical part erected in the plate-like part, and a through hole into which a male screw is inserted into the hole of the second member. A hole is formed from the plate-shaped part side to the tip of the cylindrical part, and a pair of first groove parts parallel to each other in a direction intersecting the through hole are formed on the outer periphery of the front end side of the cylindrical part; A bush main body having an insulating property is formed with a second groove intersecting with the first groove, and a notch having a pair of edges inserted into either one of the first and second grooves is formed. a hole portion formed in the first member, the hole portion having a holding portion that clamps between the mounting portion a plate nut which is biased toward the mounting portion and has a female thread that is screwed into the male thread; The edge portion is inserted into one of the first and second grooves of the cylindrical portion inserted into the bushing body, and the female thread of the plate nut is inserted into the through hole. 1. An insulating bushing comprising: an insulating holder positioned at a position to be screwed into the insulating bushing.
