Abstract
振動やノイズの発生を招来することなく耐久性を向上させることができる車両用ディファレンシャル装置を提供する。 ピニオンシャフト56のピニオンギヤ60を支持する支持部68およびそのピニオンギヤ60のピニオンシャフト56が嵌め入れられる嵌入穴66の少なくとも一部が、外周側ほど小径となるテーパ面70、72であることから、駆動力がディファレンシャルケース50からピニオンシャフト56およびそれに回転可能に支持されたピニオンギヤ60を介してサイドギヤ58l、58rへ伝達されるときにおいて、ピニオンギヤ60はそのサイドギヤ58l、58rとの間の噛合い反力に従ってピニオンシャフト56の軸方向外側へ移動させられるので、トルクの伝達負荷が増大するほどピニオンシャフト56とピニオンギヤ60との間の嵌合クリアランスCが拡大されて高い耐久性が得られる。
