    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.

    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 vehicle comprises a bumper reinforcement extending in a vehicle width direction and a shock absorbing member fixed to a front face of the bumper reinforcement and extending in the vehicle width direction along the bumper reinforcement. The shock absorbing member comprises a base portion extending vertically along the front face of the bumper reinforcement and a projection portion extending forward from a lower end portion of the base portion and being resiliently-downward deformable relative to the base portion. Thus, the vehicle comprising the shock absorbing member provided in front of the bumper reinforcement with the leg-flicking function for the pedestrian protection can be provided.

    Abstract translation: 车辆包括沿车宽方向延伸的保险杠加强件和固定到保险杠加强件的前表面并沿着保险杠加强件在车辆宽度方向上延伸的减震构件。 冲击吸收构件包括沿着保险杠加强件的前表面垂直延伸的基部和从基部的下端部向前延伸并相对于基部弹性向下变形的突出部。 因此，可以提供包括设置在保险杠加强件前面的减震构件的车辆以及用于行人保护的腿部弹跳功能。
