Abstract

 一端開放孔１０を有する筒状のカバー１に対して前記一端開放孔１０から先端面２０を突出させる態様でピアスパンチ２を移動不能に遊挿させている。前記カバー１とピアスパンチ２相互間に筒状のストリッパー３を上記一端開放孔１０から抜き取り可能に設けると共に、当該ストリッパー３を付勢手段４により一端開放孔１０からピアスパンチ２よりも多く突出させ、前記付勢手段４の付勢力に抗したストリッパー３への押し込みにより当該ストリッパー３の突出端に形成した貫通孔３０からピアスパンチ２の先端面が突出するパンチャーである。カバー１からストリッパー３が抜けるのを阻止する抜止手段６が、カバー１に対して着脱可能に設けられている。
