- 雄ねじ部を有し、この雄ねじ部の上端部に前記雄ねじ部よりも径が大きい頭部が形成され、この頭部の上端面に形成されている係合凹部に工具を係合させて、前記雄ねじ部を、油圧機器の透孔に形成された雌ねじ部に締め付けることによって、前記頭部の下縁部に形成された環状のシール部を、前記雌ねじ部の一端側に形成された漏斗状の傾斜内周面に圧接させることができる金属製の油圧機器用埋め栓において、
前記シール部の上側周面部が、当該シール部から前記頭部の上端部側に向かうに従って拡径するテーパ部として形成され、前記シール部と前記雄ねじ部の上端部との間に環状のくびれ部が形成され、
前記頭部の上端面から前記シール部までの頭部高さを、前記雄ねじ部の呼びの値で除算して得られる頭部高さの無次元化値が0.4〜0.7であることを特徴とする油圧機器用埋め栓。 - 前記シール部の下側周面部に下向きの傾斜外周面が形成され、
この傾斜外周面は、前記シール部から前記雄ねじ部側に向かうに従って縮径し、前記雄ねじ部の中心軸に垂直な水平面に対して7°〜20°のぬすみ角度を成すことを特徴とする請求項1記載の油圧機器用埋め栓。 - 環状の前記くびれ部の曲率半径は、下限値が0.2mmであり、上限値が0.1に雄ねじ部の呼びの値を乗算して得られた値であることを特徴とする請求項1又は2記載の油圧機器用埋め栓。
- 前記頭部に形成された前記係合凹部に対して工具を係合させることができる深さを、前記雄ねじ部の呼びの値で除算して得られる係合凹部深さの無次元化値が0.30〜0.33であることを特徴とする請求項1乃至3のいずれかに記載の油圧機器用埋め栓。
- 前記シール部の上側周面部に形成された前記テーパ部のテーパ角度が略40°であり、
