- 車軸の端部に突設された軸部に対し該軸部より車幅方向外側まで張り出すハブをユニットベアリングを介して回転自在に外嵌装着し、前記車軸の内部に軸部側からドライブシャフトを挿し込み且つその反挿し込み側の端部に備えられたフランジ部分を前記ハブの車幅方向外側に締結して該ハブを前記ドライブシャフトを介し回転駆動し得るようにした軸受構造において、前記ハブ内における前記ユニットベアリングと前記ドライブシャフトのフランジ部分とに挟まれた空間に、前記ハブの内周面に全周に亘り嵌合し且つその半径方向内側に向け壁面を成して該壁面の半径方向内側の端部を前記ハブの車幅方向外側の端部に位置するよう形成した潤滑剤保持壁を設け、該潤滑剤保持壁と前記ユニットベアリングとの間に潤滑剤を予め充填して該ユニットベアリングにおける車幅方向外側のオイルシールの摺動面に対し前記潤滑剤が常に供給されるように構成したことを特徴とする軸受構造。
- ハブの内周面における車幅方向外側端に潤滑剤保持壁の外周部を嵌合させるための段差部を形成すると共に、該段差部に嵌合させた潤滑剤保持壁の外周部をドライブシャフトのフランジ部分により挾圧保持し得るように構成したことを特徴とする請求項1に記載の軸受構造。
