The vehicle includes a side member 1, a cross member 2, an engine 3, a fan 4, a radiator 5, an intercooler 6, and a guide structure 7.

  The side member 1 is a member that extends in the front-rear direction of the vehicle. The side member 1 is made of metal and has a U-shaped cross section. The plurality of side members 1 are parallel to each other. The cross member 2 is a member provided orthogonal to the plurality of side members 1 between the plurality of side members 1. The cross member 2 is made of metal and has a U-shaped cross section. The engine 3 is a diesel engine for vehicles, for example. The engine 3 is fixed to a cross member 2 provided at the lower part of the engine 3.

  The fan 4 is a device for cooling the engine 3. The fan 4 is provided on the front side of the engine 3. The fan 4 is an electric fan that is coupled to the engine 3 via a shaft and is driven to rotate by receiving power from the engine 3. The fan 4 operates when the vehicle is running.

  The fan 4 sucks air from the front side of the fan 4 and blows air to the rear side of the fan 4. Specifically, the fan 4 sucks the air on the front side of the radiator 5 and the intercooler 6 and exhausts the air toward the engine 3 on the rear side. The fan 4 can cool the engine 3 by exhausting the air sucked by the fan 4 to the engine 3 side.

  The radiator 5 is a device for cooling the cooling water of the engine 3. The radiator 5 is provided on the front side of the fan 4. The cooling water is circulated between the radiator 5 and the engine 3. The radiator 5 cools the cooling water heated when passing through the engine 3. The radiator 5 cools the cooling water by exchanging heat between the air flowing in from the front (for example, traveling wind generated when the vehicle is traveling forward) and the cooling water that has passed through the engine 3. The radiator 5 is fixed to the cross member 2 provided near the lower portion of the radiator 5 using a bracket.

  The intercooler 6 is a device for cooling the air circulated from the turbocharger. The intercooler 6 is provided on the front side of the radiator 5. The intercooler 6 cools the air circulated from the turbocharger by exchanging heat between the air flowing in from the front (for example, traveling wind) and the air circulated from the turbocharger.

[Detailed configuration of guide structure 7]
The guide structure 7 is a structure for improving the cooling effect of the intercooler 6. Specifically, the guide structure 7 is a guide structure that creates a flow of air ahead of the intercooler of the vehicle, and a guide for preventing air heated by the engine 3 from flowing into the front of the intercooler 6. Structure.

  The guide structure 7 includes a bracket 71, a flow rate suppressing member 72, and a fixing member 73. The bracket 71 is made of metal, is located on the side or upper side of the intercooler 6, and extends in the front-rear direction of the vehicle. Specifically, as shown in FIGS. 1 to 3, the rear end portion of the bracket 71 in the front-rear direction of the vehicle is fixed to the side surface of the radiator 5 by, for example, rivets. Further, the front end portion of the bracket 71 in the vehicle front-rear direction is located in front of the front surface of the intercooler 6. For example, the bracket 71 is located outside the side surface of the intercooler 6 in the vehicle width direction of the vehicle.

  The flow rate suppressing member 72 is a member that is located in front of or on the side of the intercooler 6 and that reduces the amount of air heated by the engine 3 flowing in front of the intercooler 6. The flow rate suppressing member 72 is a plate-like member having a rectangular shape. The flow rate suppressing member 72 extends in the vehicle front-rear direction and the vehicle vertical direction. The flow rate suppressing member 72 is, for example, a sponge. The flow rate suppressing member 72 is formed of a softer material than the bracket 71 so that the user can be protected even if the user collides with the peripheral parts during assembly work.

  The flow rate suppressing member 72 is fixed near the front end of the bracket 71. The position where the flow rate suppressing member 72 and the bracket 71 are fixed is forward of the front surface of the intercooler 6. As shown in FIG. 3, the rear portion of the bracket 71 extends in the same direction as the vehicle front-rear direction. Further, the portion near the front end of the bracket 71 is inclined at a predetermined angle with the rear portion of the bracket 71. The flow rate suppressing member 72 is fixed along the side surface of the portion near the front end of the bracket 71, and is inclined at a predetermined angle with respect to the vehicle front-rear direction. The front end of the flow rate suppressing member 72 is located outside the rear end of the flow rate suppressing member 72 in the vehicle width direction of the vehicle.

  The plurality of fixing members 73 are members that fix the flow rate suppressing member 72 to the bracket 71. The plurality of fixing members 73 are provided at different positions in the longitudinal direction of the vehicle. Specifically, as shown in FIG. 2, the plurality of fixing members 73 are provided at different positions in the vehicle front-rear direction and at different positions in the vehicle height direction. For example, as shown in FIG. 2, there are two fixing members 73. One fixing member 73 is located in front of the bracket 71 and near the lower end. The other fixing member 73 is located behind the one fixing member 73 in the vehicle front-rear direction and above the vehicle height direction.

  Thus, the guide structure 7 has a plurality of fixing members 73 located at different positions in the vehicle front-rear direction. As a result, the guide structure 7 has a plurality of flow rate suppression members 72 that receive traveling air and air heated by the engine 3 as compared with the case where the plurality of fixing members 73 are positioned at the same position in the vehicle front-rear direction. It is possible to suppress fluttering by swinging in the vehicle width direction of the vehicle starting from a straight line connecting the fixed members 73 of the vehicle.

  As shown in FIG. 4, the fixing member 73 has a head portion 730, a shaft portion 731, and a protrusion 732. The fixing member 73 is made of resin, for example. The head 730 has an outer diameter larger than the inner diameter of the holes formed in the bracket 71 and the flow rate suppressing member 72. The head 730 has a circular shape, for example. The shaft portion 731 is a portion that can pass through holes formed in the bracket 71 and the flow rate suppressing member 72. The shaft portion 731 has, for example, a cylindrical shape.

  The protrusion 732 is a portion formed at the tip of the shaft portion 731 so as to be able to pass through holes formed in the bracket 71 and the flow rate suppressing member 72. The protrusion 732 has, for example, a truncated cone shape. The outer diameter of the protrusion 732 is larger than the inner diameter of the holes formed in the bracket 71 and the flow rate suppressing member 72.

  Further, the distance between the position where the head portion 730 contacts the shaft portion 731 and the position of the protrusion 732 on the head portion 730 side is, for example, equal to or less than the thickness of the flow rate suppressing member 72. The flow rate suppressing member 72 is fixed to the bracket 71 by the fixing member 73 being pushed and inserted into the holes formed in the bracket 71 and the flow rate suppressing member 72. As a result, the guide structure 7 can be fixed to the bracket 71 without being damaged by strongly tightening the sponge flow rate suppressing member 72.

  In the present embodiment, the number of the plurality of fixing members 73 is two, but the number of the plurality of fixing members 73 is arbitrary. Of the plurality of fixing members 73, one fixing member 73 is positioned in front of the bracket 71 and near the lower end, and the other fixing member 73 is rearward and upward with respect to the one fixing member 73. However, the one fixing member 73 is positioned in front of and in the vicinity of the upper end of the distal end portion of the bracket 71, and the other fixing member 73 is positioned behind and below the one fixing member 73. It may be.

  Further, although the portion near the front end of the bracket 71 and the flow rate suppressing member 72 are inclined at a predetermined angle with respect to the vehicle front-rear direction, the bracket 71 and the flow rate suppressing member 72 are in the same direction as the vehicle front-rear direction. It may be stretched.
