To provide a hub structure which is easier in assembling and dismantling even under a condition that a space of the hub structure is limited.SOLUTION: A hub structure 10 comprises: an axle housing 11; a hub 12 having an insertion hole 27 into which the axle housing 11 is inserted in a vehicle width direction; an inner bearing 14 interposed between the hub 12 and the axle housing 11 in the insertion hole 27, and rotatably supporting the hub 12 to the axle housing 11; and an inner seal 15 arranged between the hub 12 and the axle housing 11 in the insertion hole 27, and arranged inside the inner bearing 14 in the vehicle width direction. A spacer 65 is arranged between the inner bearing 14 and the oil seal 15 in the insertion hole 27, and the spacer 65 has an outside end face 71 which can abut on an inside end face 56A of an inner race 56 possessed by the inner bearing 14.SELECTED DRAWING: Figure 2 【課題】ハブ構造のスペースが制約される条件であっても、組立や分解がより容易なハブ構造の提供にある。【解決手段】アクスルハウジング１１と、アクスルハウジング１１が挿通される車幅方向の挿通孔２７を有するハブ１２と、挿通孔２７にてハブ１２とアクスルハウジング１１との間に介在され、ハブ１２をアクスルハウジング１１に対して回転可能に支持するインナベアリング１４と、挿通孔２７にてハブ１２とアクスルハウジング１１との間に設けられ、車幅方向においてインナベアリング１４よりも内側に設けたオイルシール１５と、を備えるハブ構造１０である。挿通孔２７においてインナベアリング１４とオイルシール１５との間にスペーサ６５が設けられ、スペーサ６５は、インナベアリング１４が有するインナレース５６の内側端面５６Ａに当接可能な外側端面７１を有した。【選択図】 図２
