Abstract: A front vehicle-body structure is provided that is lightweight and reduces an impact load transmitted to lower limbs of an occupant. Embodiments include a transmission disposed in a vehicle front portion, a dash lower panel dividing an inside from an outside of a vehicle cabin in a vehicle rear of the transmission, and an organ type accelerator pedal disposed on a vehicle-width-direction inner side of the dash lower panel opposed to the transmission. The dash lower panel includes a panel rear portion in which the accelerator pedal is arranged, a panel front portion extending from the panel rear portion to a vehicle front upper side, and a fragile portion extending in a vehicle width direction along a boundary between the panel rear portion and the panel front portion, which is fragile compared to the panel rear portion and the panel front portion.

Abstract: A torsion beam type of rear suspension comprising a pair of right-and-left trailing arms and a torsion beam. A floor under cover for airflow straightening is attached to a portion of a vehicle body in front of the rear suspension so as to cover a vehicle-body lower face. A cover-support bracket is laid between a rear portion of a side sill and an inward side, in a vehicle width direction, of an arm pivot of the trail arm. A portion of the floor under cover which is positioned in the vicinity of its rear end is engaged with the cover-support bracket such that a rear end portion of the floor under cover is extended from an inward-side edge of a front portion of a rear wheel house to an inside of the rear wheel house.

Abstract: A garnish is provided with a protrusion portion which protrudes outwardly, in a vehicle width direction, so as to suppress a side-face airflow flowing below a door maximum-width portion of a side portion of a cabin from going around below a vehicle floor. A plate-shaped tire deflector is provided at a lower end portion of a front edge of a rear wheel house which corresponds to a position, in a vertical direction, of a rear end portion of the protrusion portion, wherein the tire deflector is configured to deflect a side-face airflow flowing above the protrusion portion such that the side-face airflow is turned toward an outward side, in the vehicle width direction, so as not to flow into the rear wheel house and adheres to a tire-wheel outer face.

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: A vehicle underbody structure includes a catalyst disposed in a front portion of an exhaust pipe; a cover member for covering the catalyst from above; and a heat insulator disposed inside a tunnel portion behind the catalyst and configured to cover the exhaust pipe from above. The heat insulator is disposed away from the tunnel portion by a predetermined gap in an up-down direction. A front portion of the heat insulator and a rear portion of the cover member are disposed in such a way as to overlap each other. A front end of the heat insulator is disposed on the upper side with respect to a rear end of the cover member.

Abstract: A tire deflector device configured such that a deflector is disposed on a bottom portion of a vehicle in front of a front wheel is provided. The deflector includes a guide surface extending substantially horizontally in a vehicle longitudinal direction, and a vertical wall portion including a surface extending downwardly on a rear portion of the guide surface and extending in a vehicle width direction. An angle defined by a lower portion of a vertical wall portion including at least a lower end of the vertical wall portion and an imaginary orthogonal plane orthogonal to the guide surface lies within a range from 20 degrees to 45 degrees.

Abstract: A torsion beam type of rear suspension comprising a pair of right-and-left trailing arms and a torsion beam connecting the trailing arms is provided. A floor under cover for airflow straightening is attached to a portion of a vehicle body in front of the rear suspension so as to cover a vehicle-body lower face. A arm cover is attached to a lower portion of the trailing arm so as to cover a lower face of the trailing arm. The arm cover is provided with an arm-cover enlarged portion which is configured to protrude outwardly, in a vehicle width direction, from the trailing arm in a vehicle bottom-face view. The floor under cover is provided with a floor-under-cover enlarged portion such that a rear end portion of the floor under cover faces closely to a front edge of the arm-cover enlarged portion.
