Abstract

　掘削時の衝撃や係止ピンが挿抜方向に押し出されるような場合でも、係止ピンが移動しないように係止ピンを強固に固定することが可能な掘削工具を提供する。 　取付孔部３２を備えた工具本体２０と取付部材４０とを有する掘削工具１０において、取付部材４０には取付孔部３２に挿入される取付軸部４５が設けられ、取付軸部４５の外周面に取付軸部４５の延在方向に交差する凹溝４６が形成され、工具本体４０には、取付孔部３２の延在方向に交差する方向に延びて一部が取付孔部３２を貫通するピン孔３３が形成され、ピン孔３３には、取付孔部３２に挿入された取付軸部４５の凹溝４６に係合する係止ピン５６が挿入されており、ピン孔３３の開口部には、剛性体からなり、係止ピン５６の端面に当接して固定する固定部材５０と、この固定部材５０をピン孔３３の延在方向に係止して固定する係止部３７とが設けられている。
