- それぞれ凹部と凸部とが設けられた複数の板材を側圧リング内に積載し、隣接する板材の前記凹部と前記凸部とを重ね合わせ、かつ前記凹部と前記凸部をかしめて積層体を製造する製造方法において、
前記板材の外径よりも小さい前記側圧リングの内径部との間で第1摩擦力を発生させるように形成された外側周面と、前記側圧リングから前記側圧リングの中央へ延出する加圧部材が配置できるように前記外側周面よりも前記板材の内部に向かって形成されたスロット部と、前記加圧部材の先端との間で第2摩擦力を発生させるように形成された前記スロット部の内側周面とを備えた前記板材に対して、
前記側圧リングの内径部で前記板材の外側周面に第1摩擦力を発生させ、かつ前記加圧部材の先端で前記スロット部の内側周面に第2摩擦力を発生させた状態で前記かしめを行うことを特徴とする積層体の製造方法。 - 前記板材の積層面の中央部から前記外側周面までの距離Rと、前記板材の凸部と他の板材の凹部とのかしめ部分の中央部から前記板材の積層面の中央部までの距離rが、0.4R<r<0.7Rを満たすことを特徴とする請求項1記載の積層体の製造方法。
