Claims

[Scope of utility model registration request]

A bushing in which a center conductor is inserted into an insulator tube having a step formed in the middle portion is passed through a small diameter portion of the insulator tube through a mounting hole of an electrical device, and is fastened to an annular groove formed in the small diameter portion of the insulator tube. In the case where a ring is attached to the above-mentioned mounting hole, the fastening ring has a plurality of claws formed by making a number of cuts in the inner circumferential plane part, and these claws fit into the annular groove. A bushing mounting device, characterized in that the bushing is engaged with the peripheral edge of the mounting hole to support the bushing.
