The cooling unit 47 is disposed in a rearward inclined posture so as not to interfere with the suspension cross member 45 and the power steering device 46 from the lower side to the rear side of the intermediate cross member 25.

  Although not shown, an air introduction port for introducing running air is formed in the bumper member 24 in order to cool at least the radiator of the cooling unit 47, and further, the running air is sent from the air introduction port to the cooling unit 47. An air duct for guiding may be provided. In the engine room 4, vehicle equipment such as an oil cooler, an air cleaner, and a battery (not shown) are arranged in a predetermined arrangement.

The front structure 20 of the vehicle 1 described above has the following effects.
Since the foot wiper member 32 for protecting the pedestrian extending in the vehicle width direction is disposed below the bumper rain 23, when the pedestrian's foot hits the foot wiper member 32 at the time of the vehicle collision, the foot wiper member 32 walks. In this case, various vehicle equipment including the engine 5 positioned at a low position can be arranged relatively far below the hood 36, so that the hood 36 has a shock absorbing function. Therefore, it is possible to improve pedestrian protection and collision safety.

  Then, the plate mounting member 30 is disposed in order to mount the license plate 31 on the front side of the bumper rain 23, and the foot wiping member 32 is supported on the plate mounting member 30, so that the plate mounting member 30 is attached to the license plate 31. It becomes possible to achieve both the support of the foot-wiping member 32, that is, the support structure of the foot-wiping member 32 can be improved.

  Since the bumper rain 23 has a vehicle width direction intermediate portion 23c that is retracted from the connecting portion 23a between the connecting portions 23a to the pair of front side frames 22, there is a limit in retracting the position of the connecting portion 23a. However, the position of the center of gravity of the bumper rain 23, which is a heavy object, can be retracted to shorten the front overhang at the center portion in the vehicle width direction. Therefore, the yaw moment of inertia of the vehicle 1 can be reduced, and the steering stability of the vehicle 1 (handling) Performance), the dead space in the front-rear direction of the engine room 4 can be reduced, and the degree of freedom of design including the shape of the bumper member 24 forming the front exterior surface of the vehicle 1 can be improved. .

  In particular, in this vehicle 1, the engine 5 is positioned rearward of the axle position of the front wheels 2 and is disposed rearward in the engine room 4 with a low center of gravity, thereby reducing the yaw moment of inertia and improving the steering stability. However, this improvement can be further achieved by the vehicle width direction intermediate portion 23c of the bumper rain 23, and the rear placement of the engine 5 allows the conventional bumper rain in the engine room 4 to be dead in the front-rear direction. Although the space tends to increase, the above-described effect can be exhibited while reliably reducing the dead space.

  Since the plate mounting member 30 is disposed on the front side of the vehicle width direction intermediate portion 23a of the bumper rain 23, the space recessed rearward on the front side of the vehicle width direction intermediate portion 23a is effectively used for the arrangement of the plate mounting member 30. Thus, the visibility of the license plate 31 can be improved.

  Since the bumper member 24 has the bumper member vehicle width direction intermediate portion 24c retracted along the vehicle width direction intermediate portion 23c, the bumper member 24 is recessed rearward in the vehicle width direction central portion of the bumper member 24 to design the bumper member 24. The license plate 31 can be disposed outside the bumper member 24 without being largely separated from the bumper rain 23 forward.

  Since the license plate 31 is mounted so as not to protrude forward from the frontmost end position of the bumper rain 23, an obstacle such as a pedestrian directly hits the plate mounting member 30 via the license plate 31 at the time of a vehicle collision. Further, the foot wiper member 32 is arranged so as to protrude forward from the frontmost end position of the bumper rain 23, so that the foot of the pedestrian hits the foot wiper member 32 before hitting the bumper rain 23. In this way, the function of the foot wiper member 32 can be reliably exhibited.

  The bumper rain 23 has an intermediate retreating portion 23e that is retreated so as to be positioned rearward of the front end portion of the front side frame 22 in the vehicle width direction intermediate portion 23c. The bumper rain 23 is more than the connecting portion 23a. Since the vehicle width direction outer side portion 23d has an outer retreating portion 23f that is retreated so as to be located rearward of the connecting portion 23a, the center of gravity of the bumper rain 23 is further retreated, and the front overhangs at both end portions in the vehicle width direction The front overhang at the center in the vehicle width direction can be shortened, the yaw moment of inertia of the vehicle 1 can be reduced, the steering stability of the vehicle 1 can be improved, and the degree of freedom in the design of the bumper member 24 can be further improved. .

  Since a pair of crash cans 28 capable of absorbing a collision load is attached to the front end portions of the pair of front side frames 22, and the bumper rain 23 is connected to the pair of crash cans 28, an intermediate retreating portion 23e of the bumper rain 23 is further provided. Since the intermediate cross member 25 and the intermediate cross member 25 are connected via the intermediate crush can 29 capable of absorbing the collision load, the impact absorption performance can be improved and the collision safety can be improved.

  Since the frame front side portion 23b, which is the foremost end portion of the bumper rain 23, has a connecting portion 21a, the position of the connecting portion 21a is not retracted from the conventional position, but the center of gravity of the bumper rain 23 is retracted, thereby causing a front overhang. It can be partially shortened, and when a collision occurs, the collision weight is often input from the frame front side portion 23b of the bumper rain 23.
