In an automobile hood (1), an outer plate (3) and an inner plate (2) are joined by a plurality of dot-shaped joining parts (20). The automobile engine cover (1) is provided with a first direction joint part row (30) and a second direction joint part row (40), wherein the first direction joint part row (30) is formed by arranging a plurality of joint parts (20) at intervals in the width direction (X), and the second direction joint part row (40) is formed by arranging a plurality of joint parts (20) at intervals in the length direction (Y) orthogonal to the width direction (X). The curvature (1/R1) of a region of the outer plate (3) corresponding to the first-direction joining section row (30) in the direction along the first-direction joining section row (30) is smaller than the curvature (1/R2) of a region of the outer plate (3) corresponding to the second-direction joining section row (40) in the direction along the second-direction joining section row (40). The interval (X1) between the joining parts (20) in the first direction joining part row (30) is larger than the interval (Y2) between the joining parts (20) in the second direction joining part row (40).
在汽车发动机罩(1)中,外板(3)与内板(2)由点状的多个点状的接合部(20)接合。汽车发动机罩(1)具有多个接合部(20)相互隔开间隔地在宽度方向(X)上排列而成的第1方向接合部列(30)和多个接合部(20)相互隔开间隔地在与宽度方向(X)正交的长度方向(Y)上排列而成的第2方向接合部列(40)。外板(3)的与第1方向接合部列(30)相对应的区域的沿着第1方向接合部列(30)的方向上的曲率(1/R1)比外板(3)的与第2方向接合部列(40)相对应的区域的沿着第2方向接合部列(40)的方向上的曲率(1/R2)小。第1方向接合部列(30)中的接合部(20)彼此的间隔(X1)比第2方向接合部列(40)中的接合部(20)彼此的间隔(Y2)大。
