To provide an axle support structure capable of vehicle widthwise positional adjustment between a retainer and a hub bearing to performed easily, and further reducing size and weight of the retainer and hub bearing.SOLUTION: An axle support structure A which is connected to a vehicle body side member 1, supports an outer ring member 31 of a hub bearing 3 via a retainer 2 having a center hole 22, and integrates an axle 4 passing through the center hole 22 with an inner ring member 32 of the hub bearing 3 so as to axially rotatably support the axle 4. An enlarged diameter portion 221 having a contact surface 221a in contact with a vehicle widthwise inner end surface 313 of the outer ring member 31 is provided in a vehicle widthwise outer portion 22a of the center hole 22.SELECTED DRAWING: Figure 1
【課題】リテーナとハブベアリングとの車幅方向位置調整が容易であり、かつリテーナやハブベアリングのさらなる小型化、軽量化が可能なアクスルの支持構造を提供する。【解決手段】車体側部材1に連結されるとともに中心孔22を有するリテーナ2を介してハブベアリング3の外輪部材31を支持し、上記ハブベアリング3の内輪部材32に上記中心孔22を通過するアクスル4を一体化させて当該アクスル4を軸転可能に支持するアクスルの支持構造Aにおいて、上記中心孔22の車幅方向外方部22aに、上記外輪部材31の車幅方向内端面313が当接する当接面221aを有する拡径部221を設けた。【選択図】 図1
