Abstract: A panel joint structure suppresses stress concentration on a flange corner section-side end-portion of an adhesive during application of a peeling load. A first panel member includes a panel body section, a corner section, and a first flange section. A second panel member is arranged to oppose the first flange section. A joint section joins the first flange section and the second panel member in a contact state thereof, and an adhesive continuously provided in a longitudinal direction of the corner section adheres the first flange section to the second panel member. The first panel member includes a load transmission section near a joint section, and the load transmission section is provided between the panel body section and the first flange section, and an angle θ2 thereof that is defined with the panel body section is larger than an angle θ1 defined by the panel body section and a portion in a short direction of the first flange section. A flange distal end-side end-portion of the load transmission section in the short direction of the flange section is disposed in a region between a corner section-side end-portion and a distal end-side end-portion of the joint section in the short direction of the first flange section.

Abstract: A fragile portion is provided at a portion of a suspension arm which is positioned near a vehicle-body attachment portion. The fragile portion is configured such that when a load which is greater than a specified magnitude is inputted to a front wheel from a vehicle forward side, the suspension arm is bent at the fragile portion, whereby the front wheel is rotated rearwardly around the fragile portion.

Abstract: A joint structure increases fastening force between a first member and a second member while preventing peeling of an anti-rust coating film of the first member. The joint structure includes the first member in which the anti-rust coating film is formed by electrodeposition on a surface of a metallic base material; the second member that contacts the first member; and fastening members that fasten the first and second members together. Plural convex portions, each having a height less than a thickness of the electrodeposition coating film, are disposed in at least a part of a surface of the second member that contacts the first member. The first member and the second member are fastened by the fastening members such that the electrodeposition coating film of the first member and the convex portions mesh with each other without the base material of the first member contacting the convex portions.
