PROBLEM TO BE SOLVED: To provide a structure of a wheel support rolling bearing unit which hardly causes initial grease leakage at a slide-contact part between a tip and a mating face of a side lip, and its manufacturing method.SOLUTION: In a state that tips of inside/outside side lips 27, 28 are not made to contact with an inside face of a rotation-side flange in an axial direction yet, grease 33b, 33c for forming a fluid lubrication film is applied on a portion deviated from the tips out of internal peripheral faces of the inside/outside side lips 27, 28 in advance. In this state, the tips of the inside/outside side lips 27, 28 are made to contact with the inside face of the rotation-side flange in the axial direction while having fastening margins over the whole periphery, and the grease 33b, 33c is made to contact with the inside face of the flange.SELECTED DRAWING: Figure 3

    【課題】サイドリップの先端部と相手面との摺接部で初期グリース漏れが起こりにくい、車輪支持用転がり軸受ユニットの構造及びその製造方法を実現する。【解決手段】回転側フランジの軸方向内側面に対し、内側、外側各サイドリップ27、28の先端部を接触させる前の状態で、内側、外側各サイドリップ27、28の内周面のうち、先端部から外れた部分に、流体潤滑膜を形成する為のグリース33b、33cを塗布しておく。この状態で、回転側フランジの軸方向内側面に対し、内側、外側各サイドリップ27、28の先端部を全周に亙り締め代を有する状態で接触させると共にグリース33b、33cを接触させる。【選択図】図3
