To provide a fastening device for a vehicle capable of enhancing the strength performance with a simple structure.SOLUTION: A fastening device 100 includes: a hook bracket 104 swollen downward from a vehicle body undersurface 108; and a towing hook 106 joined to the hook bracket 104. A backward swollen part 122 swollen backward is formed in a rear wall 120 of the hook bracket 104. The backward swollen part 122 includes: an apex 132 extending in a vehicle width direction; upper ridges 128a and 128b extending upward from both ends of the apex 132 while separating from each other in the vehicle width direction, and reaching the rear wall 120; lower ridges 130a and 130b extending downward from both the ends of the apex 132 while separating from each other in the vehicle width direction, and reaching the rear wall 120; and a hook fitting groove 134 formed so as to be dented in a direction intersecting the apex 132 and to which one end of the towing hook 106 is joined.SELECTED DRAWING: Figure 2

    【課題】簡潔な構成で強度性能の向上が可能な車両用緊締装置を提供する。【解決手段】緊締装置100は、車体下面108から下方へ膨出しているフックブラケット104と、フックブラケット104に接合させたトーイングフック106とを備える。フックブラケット104の後壁120には、後方へ膨出した後方膨出部122が形成されている。後方膨出部122は、車幅方向に延びた頂部132と、頂部132の両端それぞれから互いに車幅方向に離れながら上方へ延びて後壁120に到達する上側稜線128a、128bと、頂部132の両端それぞれから互いに車幅方向に離れながら下方へ延びて後壁120に到達する下側稜線130a、130bと、頂部132に交差する方向に沿って窪むよう形成されていてトーイングフック106の一端が接合されるフック取付溝134とを有する。【選択図】図2
