PROBLEM TO BE SOLVED: To provide an exterior beam for vehicle, enabling high-accuracy dimensional control, capable of maintaining sufficient load-withstanding performance against collision and capable of achieving weight saving.SOLUTION: In an exterior beam for vehicle, the mounting holes 21f, 21b are formed at the front and rear overlapping positions to the front and rear walls 11 and 12, respectively, and the flexures 22l, 22r curving a frame member 10 halfway in a lengthwise direction are formed adjacently to the mounting holes 21f, 21b. The front side taper parts 16t, 16b are provided at the connection parts of a front wall 11, and the upper and lower walls 13 and 14, and are formed to increase the thicknesses of the upper and lower walls 13 and 14 as heading for the front wall 11. Besides, the rear side taper parts 17t, 17b are provided at the connection parts of a rear wall 12, and the upper and lower walls 13 and 14, and are formed to increase the thicknesses of the upper and lower walls 13 and 14 as heading for the rear wall 12. A width W0 is made to be 60 mm or more and 160 mm or less, and a ratio {(W1×tanθ1)/(W2×tanθ2)} is set to be in the range of 1.3 or more and 3.9 or less.SELECTED DRAWING: Figure 3

    【課題】高精度の寸法管理を可能とし、衝突に対する十分な耐荷重性能を維持でき、軽量化を図ることができる車両用外装ビームを提供する。【解決手段】前壁11と後壁12とのそれぞれに取付孔21f,21bが前後の重なる位置に形成され、取付孔21f,21bに隣接してフレーム部材10の長さ方向の途中を曲げた曲げ部22l,22rが形成されており、前壁11と上壁13及び下壁14との連結部には前壁11に向かうにつれて上壁13及び下壁14の厚みを増して形成される前側テーパ部16t,16bが設けられ、後壁12と上壁13及び下壁14との連結部には後壁12に向かうにつれて上壁13及び下壁14の厚みを増して形成される後側テーパ部17t,17bが設けられ、幅W0が60mm以上160mm以下とされ、かつ、比率{(W1×tanθ1)/(W2×tanθ2)}が1.3以上3.9以下の範囲に設定される。【選択図】 図3
