    摘要： In an automobile hood 1, an outer panel 3 and an inner panel 2 are joined together by a plurality of spot-shaped joints 20. The automobile hood 1 has a first-direction joint row 30 in which a plurality of the joints 20 are arranged at an interval from each other in a cross direction X, and a second-direction joint row 40 in which a plurality of the joints 20 are arranged at an interval from each other in a longitudinal direction Y that is perpendicular to the cross direction X. A curvature 1/R1 in a direction along the first-direction joint row 30 in a region of the outer panel 3 corresponding to the first-direction joint row 30 is smaller than a curvature 1/R2 in a direction along the second-direction joint row 40 in a region of the outer panel 3 corresponding to the second-direction joint row 40. An interval X1 between the joints 20 in the first-direction joint row 30 is greater than an interval Y2 between the joints 20 in the second-direction joint row 40.

    摘要： In an automobile inner panel and an automobile panel that includes the automobile inner panel, panel rigidity of the panel is secured while achieving a weight reduction. An automobile inner panel 2 has a plurality of sub-units 10 that each include a flange 11, an inclined wall 12 continuous with the flange 11, and a bottom portion 13 continuous with inclined wall 12 and separated from the flange 11. The bottom portions 13 and 13 of the sub-units 10 and 10 which are adjacent to each other are butted against each other and are directly continuous with each other. A maximum value of a distance D1 between two of the flanges 11 and 11 of two of the sub-units 10 and 10 in which the bottom portions 13 are arranged separated from each other and which are adjacent to each other is 250 mm or less.

    摘要： An increase in the efficiency of an operation for joining an inner panel and an outer panel of an automobile hood is enabled while making the joining strength between the inner panel and the outer panel sufficiently high. An automobile hood 1 has an inner panel 2, an outer panel 3, and a plurality of linear sealer regions A in which joints 21 are arranged. A region which includes the linear sealer region A and in which both ends in a longitudinal direction L of the linear sealer region A reach the outer circumferential edge of the inner panel 2 is defined as an end-to-end region B. Each of three longest linear sealer regions A2, A4 and A3 among the plurality of linear sealer regions A is a length that is 40% or more of the length of an end-to-end region B2, B4 or B3 to which the linear sealer regions A2, A4 or A3 belongs, respectively. These three end-to-end regions B2, B4 and B3 do not intersect with each other within a region surrounded by the outer circumferential edge of the inner panel 2.
