Claims

[Claims for Utility Model Registration] (1) A countersunk nut characterized by having a penetrating screw hole provided in a truncated cone or the shaft of a cone. (2) A high-frequency heating coil body consisting of a semi-open high-frequency heating coil and a pair of insulating plates sandwiching this coil and facing each other is penetrated from one insulating plate to the other insulating plate. A countersunk screw having a countersunk portion and a threaded portion protruding from the countersunk portion, a truncated cone or a shaft of the cone having a penetrating screw hole corresponding to the threaded portion, the screw hole being connected to the tip of the countersunk screw. and a screwed countersunk nut, and the countersunk screw is
The countersunk nut is attached to an opening provided in one insulating plate to correspond to the shape of the countersunk nut, and the countersunk nut is attached to an opening provided in the other insulating plate to correspond to the shape of the countersunk nut. A high-frequency heating coil body assembled using a countersunk nut, characterized in that no protrusions are formed on the outer surfaces of both insulating plates.
