To improve torsional rigidity while suppressing weight increase.SOLUTION: An axle case structure 1 comprises an axle case body 2 which extends in a vehicle width direction of a vehicle. The axle case body has a hexagonal part 7 having a hollow hexagonal cross-sectional shape. The hexagonal part has an upper hexagonal part 10 and a lower hexagonal part 11 divided into upper and lower parts, the upper hexagonal part has a trapezoidal cross-sectional shape of which a lower bottom side is opened, and the lower hexagonal part has an inverted trapezoidal cross-sectional shape of which an upper bottom side is opened. The hexagonal part has a welding part 6R that fixes a butt part between the upper hexagonal part and the lower hexagonal part.SELECTED DRAWING: Figure 2
