To provide an axle case structure that restrains buckling deformation which occurs at a connection part of a shoulder round part on an upper surface of an axle case body which is bent downward in a convex shape by car weight and road surface reaction, and a horizontal part.SOLUTION: An axle case structure includes an axle case main body 7 having: a banjo part 3 with openings 2 formed at front and rear; horizontal parts 4 which are arranged on the left and right of the banjo part 3 and which is subjected to a car weight W; spindles 5 which are connected to outer ends in the car width direction of the horizontal parts 4 and which are subjected to a road surface reaction R; and shoulder round parts 6 connecting the banjo parts 3 and the horizontal parts 4. A ring 16 with a reinforcement flange is attached to the axle case main body 7. The ring 16 with a reinforcement flange includes: a central ring part 16a surrounding the opening 2 of the banjo part 3; and a reinforcing flange part 16b extending from the left and right in the car width direction of the central ring part 16a to a position beyond a connection part of the shoulder round part 6 and the horizontal part 4 outward in the car width direction .SELECTED DRAWING: Figure 6

    【課題】車重及び路面反力により下方に凸に曲げられるアクスルケース本体の上面の肩アール部と水平部の接続部に生じる座屈変形を抑えるアクスルケース構造を提供する。【解決手段】前後に開口2が形成されたバンジョー部3と、バンジョー部3の左右に配置され車重Wが加わる水平部4と、水平部4の車幅方向の外端に接続され路面反力Rが加わるスピンドル5と、バンジョー部3と水平部4とを接続する肩アール部6とを有するアクスルケース本体7を備え、アクスルケース本体7に、補強フランジ付きリング16が取り付けられており、補強フランジ付きリング16は、バンジョー部3の開口2を囲繞する中央リング部16aと、中央リング部16aの車幅方向の左右から車幅方向外方に向けて肩アール部6と水平部4との接続部を越える位置まで延出された補強フランジ部16bとを有する。【選択図】図6
