To provide a cowl brace structure for a vehicle, the cowl brace structure being able to make vibration decrease performance of a steering device satisfactory and, at the same time, make impact absorption performance satisfactory in the event of front collision of a vehicle as well.SOLUTION: A cowl brace 1 is sectioned into an upper member 1a and a lower member 1b located below the upper member, each of which is connected to a cross member 4 and a cowl panel 3. The upper member 1a and the lower member 1b respectively have an upper and lower curved parts 12a, 12b, each of which is curved in the form of an upward projection as viewed from a side, in a vehicle front side area from the cross member 4 and a steering support part 2b. Both the curved parts 12a, 12b are provided with a fragile part 13 less rigid than the other portions and the lower curved part 12b is formed so as to be smaller in curvature radius than the upper curved part 12a.SELECTED DRAWING: Figure 2

    【課題】ステアリング装置の振動軽減性能を良好にしつつ、車両の前突時の衝撃吸収性能をも良好なものとすることが可能な車両のカウルブレース構造を提供する。【解決手段】カウルブレース1は、それぞれがクロスメンバ4およびカウルパネル3に接続されたアッパ部材1aおよびその下側に位置するロア部材1bに区分されており、これらアッパ部材1aおよびロア部材1bは、クロスメンバ4およびステアリングサポート部2bよりも車両前方側の領域において、側面視上向き凸状に湾曲したアッパ側およびロア側の湾曲部12a,12bを備えており、これら湾曲部12a,12bの両者には、剛性が他の部分よりも小さい脆弱部13が設けられているとともに、ロア側の湾曲部12bは、アッパ側の湾曲部12aよりも曲率半径が小さい湾曲状とされている。【選択図】 図2
