ことを特徴としている。
図1乃至図4は、本発明の第1実施形態に係る射出成形軸1を示す図である。なお、図1は射出成形軸1の使用状態を示す図である。また、図2(a)が射出成形軸1の正面図(X軸方向に沿って見た図)、図2(b)が図2(a)の矢印B1の方向から見た射出成形軸1の左側面図、図2(c)が図2(a)の矢印B2の方向から見た射出成形軸1の右側面図、図2(d)が図2(a)のA1-A1線に沿って切断して示す射出成形軸1の断面図、図2(e)が図2(a)のA2-A2線に沿って切断して示す射出成形軸1の断面図、図2(f)が図2(a)のA3-A3線に沿って切断して示す射出成形軸1の断面図である。また、図3(a)が射出成形軸1の平面図(Y軸方向に沿って見た図)、図3(b)が図3(a)のA1-A1線に沿って切断して示す射出成形軸1の断面図、図3(c)が図3(a)のA2-A2線に沿って切断して示す射出成形軸1の断面図、図3(d)が図3(a)のA3-A3線に沿って切断して示す射出成形軸1の断面図である。また、図4は、図2(a)の射出成形軸1(特に、軸本体2)の一部を拡大して示す図である。
これら図1乃至図3に示すように、射出成形軸1は、軸方向一端側に形成された第1のトルク作用部としてのはすば歯車3と、軸方向他端側に形成された第2のトルク作用部としてのウォーム4と、これらはすば歯車3とウォーム4とを軸心方向に沿って一体に接続する軸本体2と、を有している。また、この射出成形軸1は、はすば歯車3の側面3aの回転中心部に丸棒状の第1ボス5が一体に形成され、ウォーム4の側面4aの回転中心部に丸棒状の第2ボス6が一体に形成されている(図2(a)~(c)参照)。このような構造の射出成形軸1は、後に詳述するように、POM(ポリアセタール)やPA(ポリアミド)等の溶融樹脂を金型7のキャビティ8内に射出することにより、一体として形成される。

以上のような本実施形態に係る射出成形軸1は、急激なトルク変動が作用したとしても、急激なトルク変動に伴うエネルギーを軸本体2の柔軟な捩れ変形によって吸収することができ、急激なトルク変動に伴う衝撃を軸本体2の捩れ変形によって緩和することができる。その結果、本実施形態に係る射出成形軸1によれば、軸方向一端側に形成されたはすば歯車3及び軸方向他端側に形成されたウォーム4に過度な負荷が作用するのを抑えることができ、軸方向一端側に形成されたはすば歯車3の歯及びこれと噛み合う他の第1はすば歯車10の歯が破損するのを防止できると共に、軸方向他端側に形成されたウォーム4の歯及びこれと噛み合う他の第2はすば歯車12の歯が破損するのを防止できる。
