物体５に対し横ずれが小さくて済むという利点がある。Reference numeral 6 is a cylindrical insulator made of synthetic resin such as nylon or phenol resin, and is fitted in the screw hole 2 of the nut body 1.
6A is a collar portion of the insulator 6, and a height h is a distance from the welding surface 4 of the nut body 1 and is larger than a protruding height of the electrode welding portion 3. (See FIG. 1 and FIG. 3) By adopting the height h of the collar portion 6A, the nut body 1 is moved to the through hole 7 of the target object 5.
It is possible to smoothly guide the inside of the nut body, and when the nut body 1 is clamped by an arc stud welding gun (not shown) and arc-welded, a tsuba is used for fine pulling of the nut body 1 in the arrow A direction. Since the portion 6A cannot be disengaged from the through hole 7, the nut body 1 can be accurately welded to a predetermined position. L is a width of the collar portion 6A and is a through hole 7 of the target object 5.
Is smaller than the diameter D of the nut body 1 and larger than the root diameter d of the screw hole 2 of the nut body 1. That is, the relationship is D>L> d. Therefore, there is an advantage that the nut body 1 can be laterally displaced with respect to the target object 5 during arc welding of the nut body 1.
８はボルトで、ナット本体１の螺孔２内に残した絶縁体
６をセルフタッピングしながら螺着する。Reference numeral 8 is a bolt for screwing the insulator 6 left in the screw hole 2 of the nut body 1 while self-tapping.
然る時、この絶縁体６はねじの緩み止め機能を発揮す
る。At this time, the insulator 6 exerts a screw loosening prevention function.
（実施例１）第４図参照 本実施例の特徴は電極溶接部３を円弧状３Ｂにして一対
対向せしめた点にある。(Embodiment 1) See FIG. 4. The feature of this embodiment is that the electrode welded portions 3 are formed into an arcuate shape 3B and are opposed to each other.
（実施例２）第５図参照 本実施例の特徴は電極溶接部３を円弧状に形成し更に細
かく複数分割した点にある。(Embodiment 2) See FIG. 5 The present embodiment is characterized in that the electrode welded portion 3 is formed in an arc shape and further divided into a plurality of pieces.
（効果） 而して、本考案は下記の如き特有の効果がある。(Effect) Therefore, the present invention has the following unique effects.
（ａ）ナット本体の螺孔に絶縁体を嵌着してあるのでア
ーク溶接時にスパッタが螺孔内に入り込むのを防止でき
る。(A) Since the insulator is fitted in the screw hole of the nut body, spatter can be prevented from entering the screw hole during arc welding.
（ｂ）電極溶接部３を突起３Ａ又は円弧状３Ｂに形成し
同心円上に複数個配設してあるのでアークの飛出を良好
に行い得、溶接を円滑に出来る。(B) Since the electrode welded portion 3 is formed in the projection 3A or the arcuate shape 3B and a plurality of the electrode welded portions 3 are concentrically arranged, the arc can be ejected well and the welding can be smoothly performed.
（ｃ）絶縁体６の形状を円筒状としてあるので、ボルト
を螺着する際、絶縁体６をセルフタッピングしながら螺
着し、この絶縁体がボルトの緩み止め作用をなす。(C) Since the insulator 6 has a cylindrical shape, when the bolt is screwed, the insulator 6 is screwed while self-tapping, and the insulator serves to prevent the bolt from loosening.
（ｄ）請求項２の記載に於いてはナット本体１を対象物
の貫通孔７内にスムースにガイド出来、又アーク溶接時
