PROBLEM TO BE SOLVED: To provide a vehicle structure capable of reducing damages on an upper side of a seal lip portion caused by rotations of a shaft-shaped rotator.SOLUTION: A vehicle structure 1 includes a case body 2 into which oil 9 is supplied; a shaft-shaped rotator 3 which has a shaft portion 30 penetrating the inside and outside of the case body 2 and a flange portion 31 provided at a part disposed on the outside of the case body 2 at the shaft portion 30; and an oil seal 41 which has a seal lip portion 41L contacting with an outer end surface 31A in a diametrical direction of the flange portion 31. A part on the case body 2 side rather than the outer end surface 31A in the flange portion 31, has a diameter-enlarged shape gradually enlarging a diameter from an outer peripheral surface 30A of the shaft portion 30, and is equipped with an inclined surface 31B spread from the outer peripheral surface 30A of the shaft portion 30 to the outer end surface 31A of the flange portion 31.SELECTED DRAWING: Figure 1 【課題】軸状回転体の回転に伴うシールリップ部の上方側の損傷を低減できる車両構造を提供する。【解決手段】内部にオイル９が供給されるケース体２と、ケース体２の内外に貫通するシャフト部３０、およびシャフト部３０におけるケース体２の外側に配置される部分に設けられるフランジ部３１を有する軸状回転体３と、フランジ部３１の径方向の外端面３１Ａに接触するシールリップ部４１Ｌを有するオイルシール４１と、を備える車両構造１である。フランジ部３１における外端面３１Ａよりもケース体２側の部分は、シャフト部３０の外周面３０Ａから徐々に径が大きくなる拡径形状となっており、シャフト部３０の外周面３０Ａからフランジ部３１の外端面３１Ａに至る傾斜面３１Ｂを備える。【選択図】図１
