重ね合せ、ここに穿設した穿孔５ａ，６ａ内にリ
ベツト１の胴部３を差し込み、この下端をかしめ
て両者５，６を継合させるのであるが、これを次
のようにして行う。
すなわち、上記のように胴部３を差し込んだ
後、その頭部２の上面を支持材７によつて押え、
胴部３の下端を加熱したかしめポンチ８で押圧し

この時、頭部２の周辺部２ｄは、頭部２の上面
の押圧により凹条部２ｂが水平となるよう及び胴
部３の下端の押圧により凹陥部２ｃ内に胴部３の
上端が突出するようにたわみ、十分な押圧力が得

そして、かしめポンチ８による押圧が終了し、
これを取除いた時、カール状に折り曲げられた胴
部３の先端は、その弾性力によつて僅かに復元す

なお、上記ポンチ１３は、銅製とした場合、熱
の伝導率が高く、リベツト１の軸径が10mm以上で
肉厚が２mm以上のものの加工に適し、黄銅製の場
合、銅製のものより熱伝導率がやや低い為、軸径
が６〜８mmで、肉厚が１〜２mmのものに適し、ス
チール製とした場合、熱伝導率が更に低い為、軸
径が６mm以下で、肉厚が１mm以下のものや、軟化
温度の低いものに適する。
また、ポンチ１３は任意の長さに設定すること
ができ、先端部の温度調節を行つて、より確実な
かしめを行うようにすることができる。
更に、第４図に示すようなワツシヤ１５を使用
することにより、締結後の緩みやガタの発生をよ

を図るようにすることができる。
すなわち、ワツシヤ１５は、同図イにおいて、
円板状で、その中央に通孔１５ａを設けると共
に、被締結物当接面側に凹部１５ｂを設け縦断面
略皿形にして、その中央部にリング状の薄肉部１
５ｃを形成したものであり、また同図ロにおいて
は、更に被締結物当接面の反対側にも凹部１５ｄ
を形成したものである。
而して第５図に示すように、リベツト１の胴部
３の下端をかしめる際、上記頭部２の周辺部２ｄ
の他に、この薄肉部１５ｃもたわむことになり、
この弾性力によつて締結後の緩みやガタの発生が
より完全に防止され、また被締結物５，６に対す

に役立つのである。
更に同図に示すように上記第４図ロに示すワツ
シヤ１５を使用すれば、リベツト１の胴部３下端
端のかしめ部が、ワツシヤ１５の凹部１５ｄ内に
収納されて美感の向上に役立つことになる。
本考案は上記のような構成であるので、リベツ
