摘要： Provided is a vehicle hood that allows a reduction in thickness of an outer panel while providing stiffness of the outer panel. A vehicle hood includes an outer panel, an inner panel, and a plurality of adhesive components. The inner panel has a plurality of beads. Each bead has a support part that supports each adhesive component. The adhesive components are provided on the support parts so as to be intermittently aligned along a specific direction. A support-part interval between the support parts adjacent to each other in an intersecting direction is smaller than an adhesive-component interval between the adhesive components adjacent to each other on the support parts.

摘要： A method for manufacturing an electric vehicle battery case includes: preparing a frame configured to define a through space inside and a flat plate made of resin; superposing and disposing the flat plate on the frame; and applying pressure to the flat plate from an opposite side from the frame to press the flat plate against the frame to cause the flat plate to swell in the through space, thereby deforming the flat plate into a tray having a bathtub shape including a bottom wall and a peripheral wall provided at a peripheral edge of the bottom wall and configured to define an opening portion, and joining by press-fitting the tray to the frame.

摘要： An inner panel of a vehicle hood has a 0.2% proof stress of 70 MPa or more and 120 MPa or less after assembling of the inner panel and completion of bake coating. An outer panel has a 0.2% proof stress of 150 MPa or more. The outer panel is made of JIS 5000 or 6000 series aluminum alloy plate material, and the inner panel is made of a JIS 3000 series aluminum alloy plate material. The inner panel has hat-shaped main beads arranged in a center portion. An elongation amount (L−L0)/L0 determined by cross-section line length L of a concave or convex portion of the main bead projected from the surface of the center portion and a line length L0 of a line segment linearly connecting ends of the portion is 0.4 δ to 0.6 δ to a breaking elongation δ in uniaxial tensile deformation.

摘要： A battery case for an electric vehicle includes a frame that has a polygonal frame shape in plan view, defines a through hole inside, and has R shapes provided on inner sides of corner parts of the polygonal frame shape. The case also includes a bathtub-shaped tray that includes a bottom wall located in the through hole, a surrounding wall that is provided around the bottom wall and defines an opening part on a side opposite to the bottom wall, and a flange that is provided at a distal end of the surrounding wall. The tray is pressure-welded to and integrated with the frame.

摘要： A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.
