摘要： A joint structure includes a first sheet member, a second sheet member overlapped with the first sheet member in a sheet thickness direction, a third sheet member overlapped in the sheet thickness direction on an opposite side of the second sheet member from a side overlapped with the first sheet member, and plural joining parts formed at locations where the first sheet member, the second sheet member, and the third sheet member overlap, so as to join the first sheet member, the second sheet member, and the third sheet member together. The plural joining parts are formed at an interval along an edge of the first sheet member and an edge of the second sheet member. The third sheet member includes a fold-back portion provided at least between the plural joining parts by folding the third sheet member back around the edge of the first sheet member and the edge of the second sheet member such that the fold-back portion is disposed on an opposite side of the first sheet member from a side overlapped with the second sheet member.

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： A stiffened panel structure (1) includes a panel-shaped component (2) and a wire (3). The panel-shaped component (2) has a panel body (21) that curves in such a manner as to be convex outward. The wire (3) has a first end portion (31) and a second end portion (32). The first end portion (31) is bonded to a first point (211) on the inner surface (21a) of the panel body (21). The second end portion (32) is bonded to a second point (212) on the inner surface (21a) of the panel body (21). The wire (3) is strained between the first point (211) and the second point (212).

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.

摘要： An automobile hood 1 has joints 20 that join an inner panel 2 and an outer panel 3. The inner panel 2 includes, for example, units 8 and 9 arranged in plurality in an aligned relationship in a cross direction X and arranged in plurality in an aligned relationship in a longitudinal direction Y. The plurality of units 8 and 9 include a plurality of joint-equipped units in which the joint 20 is provided. A predetermined first form or second form is provided in the automobile hood 1. In the first form, in some of the joint-equipped units, namely, joint-equipped units 84, 89, and 9, the joints 20 are arranged in an arrangement including a predetermined pattern P1, and in the remaining joint-equipped units 81, 85, 86, 810, 811, and 812, the joints 20 are arranged in an arrangement including a part of the predetermined pattern P1.
