PROBLEM TO BE SOLVED: To suppress concentration of stress on an end portion of a weld bead B5 serving as a junction portion between an axle housing 100 and a bracket 10.SOLUTION: A positional relationship is set so that an extension line L of a weld bead B2 that is a weld joining portion to a bottom plate member 40 formed along the lower end of each of left and right side plate parts 31a and 31b of a U-shaped member 30 intersects a weld bead B5 that is a weld joining portion between the front end of each of lower plate parts 41a and 41b of the bottom plate member 40 and an axle housing 100 (lower reinforcement member 122). Thereby, the load inputted from a bush to a bracket 10 can be received by the entirety of the weld bead B5. |
