PROBLEM TO BE SOLVED: To provide a bracket welding structure on an axle case that uniformly distributes stresses of individual welded portions of the bracket on the axle case, thereby enhancing durability of the bracket, reducing an area occupied by the bracket, and avoiding a defect of welding. SOLUTION: In the bracket welding structure, a bracket 6 mounting a suspension member connected to a vehicle body frame is welded on an expanded central portion 3 of an axle case 1. The bracket 6 includes a horizontal plate member 61 along the axle direction and a pair of vertical plate members 62 disposed orthogonally to the axle at both axle directional ends of the horizontal plate member 61. Out of these vertical plate members 62, at least one end face has a slanted portion 8 with part of the end face slanted along the expanded central portion 3, and the remaining of the end face forms a non-slanted portion 9. The vertical plate member 62 and the expanded central portion 3 are fixed by fillet welding, with the slanted portion 8 hit the expanded central portion 3 and the non-slanted portion 9 separated from the expanded central portion 3.
