Abstract: A connecting reinforcement is provided between a hinge pillar and a wheel house so as to reinforce at least around a rear face portion of the wheel house. The connecting reinforcement extends in the vertical direction along a rear face portion of the wheel house and has a closed-cross section space, in a sectional view perpendicular to the vertical direction, inside thereof. A gusset including a slant face portion which is provided at a front face thereof and configured to extend obliquely rearwardly-and-outwardly is provided in the closed-cross section space. A gap space which forms a part of the closed-cross section space is provided between the slant face portion and the rear face portion of the wheel house provided on a wheel-house side so as to face the slant face portion.

Abstract: A side body structure of a vehicle includes a hinge pillar reinforced by a reinforcement having a side surface and a front surface extending inward in the vehicle width direction from the front end of the side surface. The reinforcement is provided with upper and lower gussets for reinforcing a pair of upper and lower hinge mounting portions, respectively, for a side door. The reinforcement has a first bead portion on the side surface between the upper and lower gussets, and has a second bead portion at an edge portion that is a boundary portion between the side surface and the front surface. The second bead portion extends in an up-down direction and is recessed inward at the edge portion continuously from the side surface to the front surface.

Abstract: A vehicle-body structure of a vehicle includes a first frame forming a closed cross-section portion, a reinforcing member disposed in the closed cross-section portion and connected to the first frame, and another vehicle-body member connected to an outer surface of the first frame. A connection portion of the first frame and the reinforcing member includes a rigid joint portion where the first frame and the reinforcing member are joined, and a flexible joint portion where the first frame and the reinforcing member are joined, with a damper member being disposed therebetween. The other vehicle-body member is connected to the first frame in a manner such that at least a part of the other vehicle-body member overlaps the flexible joint portion in a thickness direction of the first frame, and has a high rigidity portion that enhances rigidity at the part that overlaps the flexible joint portion.

Abstract: A vehicle body upper structure includes a pair of first structures that constitute portions on both sides in a width direction of a vehicle body in an upper portion of the vehicle body; and a second structure that extends in the width direction and is joined at opposing ends to the first structures so as to define at least a part of a window opening, to which a windshield is attachable in cooperation with the first structures. The second structure includes a low-rigid portion that is joined to one of the pair of first structures in a first area of the one of the pair of first structures, and a high-rigid portion that is separated in distance in the width direction from the first area and that has higher rigidity than the low-rigid portion. The low-rigid portion being joined to one of the first structures via the damping material.

Abstract: There are provided a pair of roof rails, a roof panel, a front header, a pair of front pillars, and a pair of center pillars, and a pair of front inclination roof reinforcements provided at a lower face of the roof panel. Each of the front inclination roof reinforcements is configured to extend obliquely from its front portion which is joined to the front header to its rear portion which is positioned on an outward side, in a vehicle width direction, relative to the front portion and joined to a portion located in the vicinity of a joint portion of the center pillar and the roof rail. Thereby, the torsional rigidity of a vehicle body can be properly improved, so that the maneuverability/stability of a vehicle can be improved.
Abstract translation: 提供了一对屋顶导轨，屋顶板，前集水头，一对前支柱和一对中心支柱，以及设置在屋顶板下表面的一对前倾斜屋顶增强件。 每个前倾斜屋顶加强件被构造成从其前部的前部倾斜地延伸到前部集管到其后部，该后部相对于前部在车辆宽度方向上位于外侧，并且连接到 部分位于中心柱和车顶轨道的接合部分附近。 因此，可以适当地改善车身的扭转刚性，从而可以提高车辆的机动性/稳定性。

Abstract: A front vehicle-body structure includes a front wheel including a wheel; and a side sill that extends in a front-rear direction on a rear side of the front wheel and has side sill inner and outer portions positioned on vehicle-width-direction inner and outer sides, respectively. Vehicle-width-direction end portions of the inner and outer portions are joined at a joined portion formed by the vehicle-width-direction end portions abutting against each other. The inner portion has a higher buckling strength in the front-rear direction than the outer portion. The joined portion has a second joined portion extending inclined to the vehicle-width-direction outer side toward a rear side, and a first joined portion bent from the second joined portion, extending to a front side, and positioned on a front-end portion of the side sill closer to the vehicle-width-direction inner side than a center line of the wheel in the vehicle width direction.

Abstract: There are provided first and second loop-shaped structure sections which are provided to extend continuously along respective lower wall parts, respective right-and-left both side wall parts, and respective upper wall parts of a vehicle body so as to have a loop shape in a vehicle elevational view, respectively. The first and second loop-shaped structure sections are respectively positioned on an forward side and on a rearward side, in a vehicle longitudinal direction, of a damper support section. Each of these sections is formed by a closed-cross section portion where a closed-cross section is partitioned by plural members and/or a thick plate portion having a thicker plate thickness than a vehicle-body panel.
