There are provided a cowl provided to support a front windshield in an inclined state where a rear side of the front windshield is located at a higher level than a front side of the front windshield and forming a lower edge of an opening portion for arranging the front windshield and a bonnet provided in front of and above the cowl. An upper portion of the cowl comprises a first face portion to which the front windshield adheres and an inclined second face portion which extends obliquely rearwardly-and-downwardly from the first face portion, and a front end of the first face portion is positioned on a rearward side, in a vehicle longitudinal direction, of a rear end of the bonnet.

Front vehicle-body structure of vehicle

An impact absorbing member is provided below a fascia upper member (upper-face forming member) which forms an upper face of a front end portion of a vehicle. The impact absorbing member comprises a front side part which includes a front wall portion, a top wall portion, and a rear wall portion so as to have a U-shaped cross section opening downward and a flat-plate shaped rear side part which extends rearward from a lower end of the rear wall portion. A rear end portion of the rear side part is held at a radiator shroud as a vehicle-body-side member, and the rear side part is configured to slant obliquely forward and downward.

Front vehicle-body structure

A pair of right-and-left brackets which extend obliquely downward and forward from respective front portions of a pair of right-and-left side frames are provided. A stiffener which extends in a vehicle width direction below a bumper beam is attached to respective front ends of the pair of right-and-left brackets. The stiffener is configured such that its front end portion slants downward and forward and has an open cross section, and its rear end portion thereof has a closed cross section. An obstacle can be prevented from coming in below a vehicle-body front portion, and also the sufficient energy absorption in a collision and the prompt flicking-up of an obstacle can properly achieved.

Vehicle-body front structure of vehicle

A protecting member comprises a pair of right-and-left brackets extending obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener extending in a vehicle width direction below a bumper beam and attached to front ends of the brackets. The stiffener has a closed cross section extending in the vehicle width direction, and an upper face of its central portion in the vehicle width direction has a concaved portion. A lower face of the stiffener extends horizontally substantially straightly. It is preferable that the closed cross section of the central portion of the stiffener be configured such that its vertical distance is relatively small and its longitudinal width is relatively large, compared with the other part of the stiffener.

A protecting member includes a pair of right-and-left brackets which extend obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener which extends in a vehicle width direction below a bumper beam and attached to front ends of the pair of right-and-left brackets. The protecting member has a load/deformation characteristic including a first stage from a collision start, a second stage after the first stage, and a third stage after the second stage. Herein, the first stage is set so as to restrain the obstacle from coming in below a vehicle-body front portion, the second stage is set so as to absorb collision energy to restrain a local deformation of the obstacle, and the third stage is set so as to flick the obstacle up.

A support structure of a windshield of the present invention comprises a frame having an open section opening forward in a vehicle and a support member provided inside the frame and connecting an upper face portion and a lower face portion of the frame. The frame has a windshield support portion supporting a lower side portion of the windshield at part of the upper face portion. The support member includes a rear support portion attached to the upper face portion of the frame and a front support portion attached to a cowl panel at a specified location positioned in front of the rear support portion. The windshield support portion is positioned between the front and rear support portions in the vehicle longitudinal direction.

Support structure of windshield

A pair of sub frames is provided on the outside of a heat exchanger in a vehicle width direction, there is provided a stiffener which interconnects front ends of the sub frames and projects forward, and the stiffener is connected to lower portions of the sub frames. Accordingly, the sufficient attachment rigidity of the stiffener can be secured in the normal state, whereas in the vehicle collision state the stiffener can be easily separated off the sub frames without resisting improperly, so that the safety of pedestrian can be secured.

A bumper face is comprised of an upper portion and a lower portion. An opening portion is formed between the upper and lower portions. A bumper mesh is comprised of a mesh body located at the opening portion and a bumper face lower reinforcing portion that is located inside of the lower portion of the bumper face and connected to a lower end of the lower portion. The bumper mesh includes an extension portion that extends rearward from a lower end of the bumper face lower reinforcing portion and is connected to the lower portion of the shroud. Accordingly, the rearward movement of the bumper face lower reinforcing portion can be surely prevented, without increasing the number of parts, and thereby the prevention of dragging of a pedestrian can be improved.

Front structure of automotive vehicle

Disclosed is a vehicle front structure, which comprises a synthetic resin shroudformed to support a heat exchanger and mounted to a vehicle body in a front of an engine compartment, a bumper fascia disposed in a front end of the vehicle body, a plate memberwhich has a front end located adjacent to a rear surface of the bumper fascia and a rear end attached to a lower shroud section, and a connection memberwhich connects a lower end region of a lateral surface of a side shroud sectionto a non-abutted portionformed in a flangeof a bumper reinforcement. The vehicle front structure of the present invention can suppress displacement of the shroud during a frontal impact with a pedestrian or an obstacle such as a curb.

Vehicle front structure

A structure of a cowl and its vicinities is provided which is capable of, even in a vehicle which has an open cowl structure, using the open cowl structure as a member which connects the right and left bodies of the vehicle, and at the same time, realizing a structure that is useful for protecting a pedestrian. At the end part of a cowlin the vehicle rear direction, one end of a dash upper panelis connected; its other end extends below the cowland in the vehicle front direction; from its middle part in the vehicle front-and-rear directions, a cowl cross-member lowerextends in the vehicle upper direction; at the upper-end part of the cowl cross-member lowera protrusion portionis formed; and by welding it to a cowl cross-member uppera closed-section portionis formed between them. Herein, the cowl cross-member upperis thinner than the cowl cross-member lower
