PROBLEM TO BE SOLVED: To easily and surely suppress damage of a tank.SOLUTION: A rib 6 of a bracket 4 is configured so that, an end surface 12 in a plate thickness direction partitioned by end edges 11 of front and rear plate surfaces contains a rib upper end surface 13, a rib outside end surface 14, and a rib lower end surface 15 for forming corner parts 17, 18 in an adjacent state, and the rib is fixed to a vehicle body side in a posture in which the rib outside end surface 14 faces a surface 2a of the tank 2. A round bar 20 formed of a metal comprises: a vertical linear part 22 extending in a linear state along the end edges 11 on a surface of the rib outside end surface 14; curve parts 24, 25 which are curved along the corner parts 17, 18; and upper linear part 21 and lower linear part 23 extending in a linear state along the end edges 11 on surfaces of the rib upper end surface 13 and the rib lower end surface 15, these parts being integrated, and the round bar is welded to the rib 6.SELECTED DRAWING: Figure 3
