Abstract
【解決手段】硬質材料製の工具本体1の内周面に凹部17を有する取付孔16に、工具本体1より低硬度の金属材料製の連結部材2の円筒状の取付部21が挿入され、取付部21が拡径するように塑性変形させられて外周面が取付孔16の内周面と密着し、凹部17と係合して工具本体1と連結部材2とが接合され、凹部17は、取付部21の挿入方向F側に向かうに従い外周側に向かう第1壁面17aと、第1壁面17aに対向して挿入方向F側に向かうに従い内周側に向かう第2壁面17bとを有し、第1壁面17aが取付孔16の内周面と交差する位置で取付孔16の中心線に垂直な平面Sに対してなす第1傾斜角αが、第2壁面17bが取付孔16の内周面とが交差する位置で平面Sに対してなす第2傾斜角βよりも小さくされている。
