PROBLEM TO BE SOLVED: To provide an axle housing in which a triangular plate is used between upper and lower main members, the plate and the members are welded to each other, and the strength in a vicinity of welded portions of the triangular plate with the main members is not degraded even when reinforcement of weld is removed. SOLUTION: In the axle housing 21, projecting parts 3 and 4 of U-shaped section are swollen in the center, two main members 7 and 8 having straight parts 5 and 6 of U-shaped section or semi-circular section on right and left sides of the projecting parts 3 and 4 are set symmetric to each other across a triangular plate 22, facing a circular hole part 9 in the center, contact surfaces are welded, and a reinforcement ring 11 and a cover 12 are welded before and behind the circular hole part 9. A recessed part 24 or 25 is formed on the circular hole part side of the triangular plate 22 or 23. In this lightweight axle housing, the strength in a vicinity of the welded portions of the triangular plate and the main members is not degraded even when reinforcement of weld is removed.
