PROBLEM TO BE SOLVED: To improve torsional rigidity while securing a space on a lower side, in a vehicular floor brace disposed below a floor panel and reinforcing the floor panel.SOLUTION: In a vehicular floor brace, because a vertical relative position of a cylindrical body part 14 to a pair of attachment parts 16 is determined such that the lower end of the cylindrical body part 14 is positioned near a virtual plane Q contacting with the lower ends (the tips) of reinforcing flanges 56, the cylindrical body part 14 is raised relatively to the attachment parts 16, and a space on a vehicle lower side becomes larger than the cylindrical body part 14 to properly secure a minimum aboveground height H. Because the cylindrical body part 14 rises relatively to the attachment parts 16, vertical displacement between the gravity center O of the cylindrical body part 14 and attachment faces 52 of the attachment parts 16 becomes small, torsional rigidity is improved in cooperation with the fact that the attachment parts 16 include a pair of reinforcing flanges 56, and the vehicular floor brace can properly reinforce a floor panel 12 without enlarging a plate thickness or a cross section of the cylindrical body part 14. |
