Claims (4)
- ステム部を有し、シンブルの回転によってスピンドルを進退させるマイクロメータヘッドと、
前記スピンドルを進退させるように前記ステムに基端側を固着され、先端側側面に軸方向に延びる複数の窓を形成した筒状の支持本体と、
前記支持本体の内部の先端側に設けた支点部を支点として揺動させる複数の計測駒とを備え、
前記計測駒は、前記窓から突出する外側面と、前記スピンドルの先端に当接する摺動面とを有し、
前記窓から突出させた複数の前記計測駒の外側面による開角度を前記スピンドルの進退動作により可変調整することを特徴とする内角度測定具。 - 複数の計測駒の摺動面を曲面に形成し、マイクロメータヘッドのスピンドルの進退動作と一対の前記計測駒の開角度動作を比例させた請求項1に記載の内角度測定具。
- マイクロメータヘッドのスリーブの軸方向に付けた目盛と、シンブルの径方向に付けた目盛とを角度を表す目盛とした請求項1及び2に記載の内角度測定具。
- 計測駒の外側面に拡張補助具を設けた請求項1に記載の内角度測定具。
