Abstract: A frame member for a vehicle which extends in a longitudinal direction, comprises a frame body portion having a closed-cross section perpendicular to an extension direction thereof, the closed-cross section having plural vertexes, a pair of groove portions formed at a pair of side wall portions which form the closed-cross section of the frame body portion, the groove portions being recessed toward an inside of the closed-cross section, and plural flanges protruding outward from the closed-cross section. The closed-cross section is symmetrical about a point of center of gravity of the closed-cross section, including projection positions of the plural flanges, and is nonsymmetrical about all straight lines which pass through the center of gravity of the closed-cross section and are perpendicular to the longitudinal direction.

Abstract: A frame member comprises a frame body portion having a closed-cross section perpendicular to an extension direction in a specified longitudinal range, which is formed by an upper wall portion, a lower wall portion, and a pair of side wall portions, groove portions formed at the pair of side wall portions, the groove portions being recessed toward an inside of the closed-cross section, a flange protruding outward from the closed-cross section. Each of the pair of side wall portions comprises plural side wall portions which include a groove-upper wall portion extending in a vehicle width direction at an upper side, a groove-lower wall portion extending in the vehicle width direction at a lower side and facing the groove-upper wall portion, and a groove-bottom wall portion interconnecting the groove-upper wall portion and the groove-lower wall portion in a vertical direction. The plural side wall portions have substantially the same bending rigidity.

Abstract: A battery case has a pair of first frames extending in a first direction, one of longitudinal-and-lateral directions, and a pair of second frames extending in a second direction, the other of the longitudinal-and-lateral directions, and is configured in a square frame shape such that the first and second frames enclose battery cells. The first frame includes a first contact face arranged to face the second frame and a first connection portion to connect to the second frame. The second frame includes a second contact face arranged to face the first frame and a second connection portion to connect to the first frame. The first frame has a step-shaped first step portion which forms a first space where at least part of the second connection portion of the second frame is stored in least part of the first contact face is provided at the first step portion.

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 reinforcing member is provided inside a closed cross section of a front side frame at a position, in a vehicle longitudinal direction, which corresponds to a forming position of a bead. The reinforcing member extends between an outward side wall portion and an inward side wall portion of the front side frame. The reinforcing member is joined to the outward side wall portion and the inward side wall portion of the front side frame. A joint length, in the vehicle longitudinal direction, of the reinforcing member and the inward side wall portion is set to be longer than that of the reinforcing member and the outward side wall portion.

Abstract: A vehicle body structure includes a frame extending in a vehicle longitudinal direction outside a power train in a vehicle width direction, the power train being mounted on a front portion of a vehicle. The vehicle body structure further includes a load receiving portion expanding outward in the vehicle width direction from a front end of the frame and configured to receive impact load acting upon front collision of the vehicle outside the frame in the vehicle width direction, a cutout portion provided at the front end of the frame and cut out rearwardly from the front end of the frame to leave two side portions, and a connection member connecting the side portions of the cutout portion in the vehicle width direction.

Abstract: A dash cross member which extends in a vehicle width direction is provided at a dash panel. A hinge-pillar reinforcing member which rigidly connects a hinge pillar to a side sill is provided at a lower end portion of the hinge pillar. A load-transmission portion (a dash reinforcement) to transmit a load which is inputted to the hinge-pillar reinforcing member in an inward direction of the vehicle width direction to the dash cross member is provided at the dash panel.

Abstract: A frame (extension frame) extending in a vehicle longitudinal direction on an outward side, in a vehicle width direction, of a powertrain mounted at a front portion of a vehicle includes front-side and rear-side high strength portions which are spaced apart, in the vehicle longitudinal direction, from each other and a low strength portion which is positioned, in the vehicle longitudinal direction, between the both high strength portions. The low strength portion has a lower bending strength than each of the both high strength portions. A specified portion which is a part of the low strength portion is positioned on the outward side, in the vehicle width direction, of and in front of a part of the powertrain (oil pan) which is located at the same level as the specified portion of the frame.

Abstract: A reinforcing member is provided inside a closed cross section of a front side frame at a position, in a vehicle longitudinal direction, which corresponds to a forming position of a bead. The reinforcing member extends between an outward side wall portion and an inward side wall portion of the front side frame. The reinforcing member is joined to the outward side wall portion and the inward side wall portion of the front side frame. A joint length, in the vehicle longitudinal direction, of the reinforcing member and the inward side wall portion is set to be longer than that of the reinforcing member and the outward side wall portion.

Abstract: A frame (extension frame) extending in a vehicle longitudinal direction on an outward side, in a vehicle width direction, of a powertrain mounted at a front portion of a vehicle includes front-side and rear-side high strength portions which are spaced apart, in the vehicle longitudinal direction, from each other and a low strength portion which is positioned, in the vehicle longitudinal direction, between the both high strength portions. The low strength portion has a lower bending strength than each of the both high strength portions. A specified portion which is a part of the low strength portion is positioned on the outward side, in the vehicle width direction, of and in front of a part of the powertrain (oil pan) which is located at the same level as the specified portion of the frame.

A hinge-pillar reinforcing member which rigidly connects a hinge pillar to a side sill is provided at a lower end portion of the hinge pillar. A load-transmission portion (a dash reinforcement) to transmit a load which is inputted to the hinge-pillar reinforcing member in an inward direction of the vehicle width direction to the dash cross member is provided at the dash panel.
