The slit 86 can be moved rearward along the lower fastening bolt 91 (described later) penetrated by the slit 86, and the opening 86a passes through the lower fastening bolt 91 so that the slit 86 is moved from the lower fastening bolt 91 to the slit 86. Can be removed.

  A rear half 87a of the slot hole 87 is provided in a portion (outer portion) 81c of the lower support bracket 71 (vehicle body outer portion 71d) facing the welding nut 78 and extends in the vehicle longitudinal direction.

  The lower abutment portion 82 is a protruding piece that protrudes substantially horizontally from the front end of the lower support portion 81 toward the front of the vehicle body. The front portion 87b of the slot hole 87 is formed in the outer portion 82a, and the front end portion 82b is directed upward. It is bent.

The front half 87b of the slot hole 87 extends linearly from the rear half 87a of the slot hole 87 toward the front of the vehicle body.
Slot holes 87 are formed in the front half portion 87b and the rear half portion 87a.
The slot hole 87 is a guide long hole that extends linearly in the longitudinal direction of the vehicle body and is movable rearward of the vehicle body along a lower fastening bolt 91 (described later) that passes through the slot hole 87.
The slot hole 87 and the slit 86 are formed at a predetermined interval L2 in the vehicle width direction.

By causing the lower contact portion 82 to protrude from the front end of the lower support portion 81, an impact load (load, input) at the time of a light collision is applied to the front end portion 82b of the lower contact portion 82 from the front of the vehicle body toward the rear of the vehicle body. be able to.
The lower moving bracket 72 is fastened to the lower support bracket 71 by a pair of lower fastening means 73.

  The pair of lower fastening means 73 is provided on the outside of the vehicle body so that one lower fastening means 73 corresponds to the slot hole 87, and the inside of the vehicle body (vehicle center side) so that the other lower fastening means 73 corresponds to the slit 86. Is provided.

One lower fastening means 73 includes a lower fastening bolt (lower fastening member) 91 for fastening the lower moving bracket 72 to the lower support bracket 71, a lower spring member (lower elastic member) 93, and a second washer 94. .
As the lower fastening bolt 91, a bolt called a “flange bolt” in which washers 91 b are integrated is used.
Hereinafter, in order to facilitate understanding of the configuration, the washer 91b will be described as a first washer, and the washer 94 will be described as a second washer.

  Since the other lower fastening means 73 is the same constituent member as the one lower fastening means 73, the same reference numerals as those of the one lower fastening means 73 are given to the respective constituent members, and detailed description thereof is omitted.

As shown in FIGS. 8 and 9, one lower fastening means 73 is configured such that the lower fastening bolt 91 passes through the slot hole 87 in a state where the lower spring member 93 and the second washer 94 are fitted to the lower fastening bolt 91. Then, it is screwed to one weld nut 78.
The lower spring member 93 is a compression spring.

In this state, the second washer 94 is brought into contact with the outer side portion 81c of the lower support portion 81, and the lower spring member 93 is interposed between the first washer 91b and the second washer 94 in a compressed state.
In other words, the lower spring member 93 is interposed between the head 91 a of the lower fastening bolt 91 and the outer portion 81 c of the lower support portion 81 in a compressed state via the first washer 91 b and the second washer 94.

  The other lower fastening means 73 is in a state in which the lower spring member 93 and the second washer 94 are fitted to the lower fastening bolt 91, and the lower fastening bolt 91 passes through the slit 86 and the other (vehicle body inner side (vehicle body center side)). ) And a welding nut 78.

In the other lower fastening means 73, similarly to the one lower fastening means 73, the second washer 94 is brought into contact with the vehicle body center side part 81b of the lower support part 81, and between the first washer 91b and the second washer 94. The lower spring member 93 is interposed in a compressed state.
In other words, the lower spring member 93 of the other lower fastening means 73 is compressed via the first washer 91b and the second washer 94 on the head 91a of the lower fastening bolt 91 and the vehicle body center side part 81b of the lower support part 81. It is intervened in the state.

  As described above, one lower fastening means 73 is provided on the outer side portion 81c of the lower moving bracket 72, and the other lower fastening means 73 is provided on the vehicle body center side portion 81b of the lower moving bracket 72. Means 73 are provided on both sides of the lower moving bracket 72 in the vehicle width direction.

In this state, the lower fastening bolt 91 is passed through the slit 86 and the lower fastening bolt 91 is passed through the slot hole 87.
Therefore, the lower moving bracket 72 is fastened to the lower support bracket 71 by a pair of lower fastening means 73 so as to be movable rearward of the vehicle body.
Thereby, the lower left part 16c (refer FIG. 2) of the cooling system component 16 is provided in the lower beam part 32 (upper part 32b) via the lower left support mechanism 36 so that a movement to the back of a vehicle body is possible.

Here, the slot hole 87 extends in the longitudinal direction of the vehicle body.
As a result, when the lower moving bracket 72 is moved rearward (sliding), the slot hole 87 can be moved along the lower fastening bolt 91.

By providing the lower fastening means 73 on both sides of the lower moving bracket 72 in the vehicle width direction, a pair of lower fastening means 73 can be provided at the approximate center of the lower moving bracket 72 in the longitudinal direction of the vehicle body.
Therefore, it is not necessary to project the shape of the lower moving bracket 72 greatly toward the rear of the vehicle body, and the lower moving bracket 72 can be downsized.

  As described above, the lower moving bracket 72 is reduced in size, and the lower moving bracket 72 is stably slid in the desired direction (rear side of the vehicle body), so that the lower moving bracket 72 protrudes toward the rear side of the vehicle body or protrudes. The amount can be suitably suppressed.

Further, by interposing the lower spring member 93 between the lower moving bracket 72 and the head 91 a of the lower fastening bolt 91, the fastening load of the lower fastening bolt 91 can be suitably adjusted by the lower spring member 93.
Thereby, management of the load (namely, "extraction load") at the time of removing the slit 86 of the lower moving bracket 72 from the lower fastening bolt 91 is facilitated, and the performance quality can be kept good.
Furthermore, the load (ie, “moving load”) when moving the slot hole 87 of the lower moving bracket 72 along the lower fastening bolt 91 can be easily managed, and the performance quality can be kept good.

As shown in FIG. 4, according to the vehicle body front structure 10, an upper left support mechanism 35 is provided on the upper beam portion 33, and the upper left support mechanism 35 allows the upper left portion 16 a of the cooling system component 16 (see FIGS. 2 and 3). Can be supported and can move toward the rear of the vehicle.
Further, a lower left support mechanism 36 is provided in the lower beam portion 32, and the lower left support mechanism 36 can support the lower left portion 16c of the cooling system component 16 (see FIG. 2) and can move toward the rear of the vehicle body.

Therefore, when an impact load is applied to the upper left support mechanism 35 and the lower left support mechanism 36 from the front of the vehicle body, the cooling system component 16 can be moved toward the rear of the vehicle body by the support mechanisms 35 and 36.
Thereby, it is possible to prevent the cooling system component 16 from being damaged by the impact load by moving the cooling system component 16 toward the rear of the vehicle body.

Further, by allowing the cooling system component 16 to move toward the rear of the vehicle body by the upper left support mechanism 35 of the upper beam portion 33 and the lower left support mechanism 36 of the lower beam portion 32, the upper beam portion and the lower beam portion are moved rearward of the vehicle body. There is no need to move it.
Since it is not necessary to move the upper beam part 33 and the lower beam part 32 to the rear of the vehicle body, the upper beam part 33 and the lower beam part 32 can be firmly and integrally provided (attached) to ensure the rigidity of the front bulkhead 15. .
Thus, the rigidity of the vehicle body front structure 10 can be secured by the front bulkhead 15, and the vehicle body front structure 10 can be made compatible with various power units (for example, engine / transmission unit).

As shown in FIG. 10, the partition wall member 21 is disposed between the cooling system support units 20 (specifically, the lower support bracket 71 of the lower left support mechanism 36 and the lower support bracket 71 of the lower right support mechanism 36).
The partition wall member 21 is disposed in a space 38 between the lower center 16d of the lower part 16b of the cooling system component 16d and the lower beam part 32, and a plurality of bolts 101 and nuts 102 (see FIG. 12) are provided on the lower beam part 32. ) (See also FIG. 1).

In the embodiment, the bolt 101 and the nut 102 are exemplified as the fastening means for attaching the partition wall member 21 to the lower beam portion 32. However, a clip or the like may be used as other fastening means.
By using a clip as the fastening means, the workability can be further improved, and the cost can be reduced and the cost can be reduced.

Here, the space 38 is a space that avoids the left and right lower support mechanisms 36 between the lower portion 16 b of the cooling system component 16 and the lower beam portion 32.
The lower portion 16b of the cooling system component 16 includes a lower left portion 16c, a lower right portion, and a central lower portion 16d.
The lower left portion 16 c is a portion supported by the lower left support mechanism 36, and the lower right portion is a portion supported by the lower right support mechanism 36.

As shown in FIG. 11, the partition member 21 disposed in the space 38 faces the grill opening 105 disposed in front of the vehicle body from the partition member 21.
The grill opening 105 is an opening for introducing air from the front of the vehicle to the engine room 22 while the vehicle is running.

  As shown in FIGS. 10 and 12, the partition wall member 21 includes an attachment seat 111 attached to the lower beam portion 32, and a partition panel 112 that rises upward from the attachment seat 111 and partitions the space 38 in the front and rear directions. And a substantially triangular reinforcing rib 113 connecting the partition panel 112 and the mounting seat 111, and a projecting piece 114 projecting from the upper end 112a of the partition panel 112 toward the radiator 17 at the rear of the vehicle body.

The mounting seat portion 111 is disposed in the vehicle width direction along the central upper portion 32 c of the lower beam portion 32, and is attached to the central upper portion 32 c with a plurality of bolts 101 and nuts 102.
The mounting seat 111 is disposed between the lower support bracket 71 of the lower left support mechanism 36 and the lower support bracket 71 of the lower right support mechanism 36.

The partition panel 112 rises vertically upward from the rear end portion 111 a of the mounting seat portion 111, and is provided between the capacitor 18 and the radiator 17.
A partition wall member 21 is provided between the capacitor 18 and the radiator 17 by raising the partition panel 112 between the capacitor 18 and the radiator 17.
Therefore, the space 38 can be partitioned forward and backward by the partition member 21 (that is, the partition panel 112).

The partition panel 112 is disposed at a position (offset position) away from the capacitor 18 by a distance L3 rearward of the vehicle body.
That is, the partition member 21 is disposed at a position away from the capacitor 18 toward the rear of the vehicle body.

Furthermore, the partition panel 112 is disposed at a position (offset position) away from the radiator 17 by a distance L4 forward of the vehicle body.
That is, the partition member 21 is disposed at a position away from the radiator 17 toward the front of the vehicle body.

  As described above, the partition wall member 21 is provided between the capacitor 18 and the radiator 17 in the longitudinal direction of the vehicle body, so that the partition wall member 21 is disposed at a position away from the cooling system component 16 in the longitudinal direction of the vehicle body.

Here, the capacitor | condenser 18 is supported by the upper and lower capacitor | condenser support parts 62 and 85 (refer FIG. 2) which can be elastically deformed.
The radiator 17 is supported by upper and lower radiator support portions 61 and 84 (see FIG. 2) that can be elastically deformed.
Therefore, it is conceivable that the cooling system component 16 (capacitor 18 and radiator 17) vibrates in the vertical direction and interferes with the partition panel 112 due to vehicle running vibration.

Therefore, the partition panel 112 is disposed at a position (offset position) away from the capacitor 18 and the radiator 17 in the vehicle longitudinal direction.
This can prevent the condenser 18 and the radiator 17 from interfering with the partition panel 112 (the partition member 21) when the cooling system component 16 (the capacitor 18 and the radiator 17) vibrates in the vertical direction due to vehicle vibration.

Further, it is conceivable that the cooling system component 16 (the condenser 18 and the radiator 17) swings (vibrates) in the front-rear direction and interferes with the partition panel 112 when the vehicle is accelerated or stopped.
Therefore, the partition panel 112 is disposed away from the condenser 18 and the radiator 17 in the longitudinal direction of the vehicle body so as to prevent the cooling system component 16 swinging (vibrating) in the longitudinal direction from interfering with the partition panel 112. did.

In particular, the radiator 17 of the cooling system component 16 has a lower portion 17 e extending below the upper end portion 112 a of the partition panel 112.
Therefore, by separating the partition panel 112 from the radiator 17 by a distance L4 forward of the vehicle body, the lower portion 17e of the radiator 17 can be prevented from interfering with the partition panel 112.

In addition, a partition wall member 21 is provided between the capacitor 18 and the radiator 17. Therefore, the capacitor 18 is disposed on the vehicle body front side with respect to the partition member 21, and the radiator 17 is disposed on the vehicle body rear side with respect to the partition member 21.
Accordingly, by disposing only the lower portion 18c of the capacitor 18 disposed on the front side of the vehicle body from the partition wall member 21 by a distance H2 from the partition wall member 21, the capacitor 18 and the radiator 17 can be prevented from interfering with the partition wall member 21. It can be moved backward.

That is, the radiator 17 is provided on the rear side of the vehicle body from the partition member 21. Therefore, even if the lower portion 17e of the radiator 17 is extended below the partition member 21, the lower portion 17e of the radiator 17 can be moved rearward without interfering with the partition member 21.
Thereby, the shape of the radiator 17 can be formed arbitrarily and the freedom degree of design can be raised.

Thus, by disposing only the lower portion 18c of the capacitor 18 above the partition wall member 21, the capacitor 18 and the radiator 17 can be moved rearward of the vehicle body.
Thereby, for example, when an obstacle or the like collides with the front of the vehicle body, the capacitor 18 and the radiator 17 can be moved toward the rear of the vehicle body to prevent the capacitor 18 and the radiator 17 from being damaged by the collision load. .

In addition, the partition panel 112 is disposed in the space 38 between the central lower portion 16 d of the cooling system component 16 and the lower beam portion 32, and the space 38 is partitioned in the front-rear direction by the partition panel 112.
Here, as shown in FIG. 11, the partition panel 112 (that is, the partition member 21) is provided at a position facing the grill opening 105.

Therefore, the air guided toward the space 38 from the grill opening 105 can be guided (raised) to the cooling system component 16 side by the partition panel 112 (partition member 21).
Thereby, the air introduced from the grill opening 105 can be efficiently guided to the cooling system component 16 (the condenser 18 and the radiator 17), and the cooling performance of the cooling system component 16 can be ensured.

Here, since the cooling fan 17d of the radiator 17 is rotating while the vehicle is running, the air guided from the grill opening 105 into the vehicle can be guided to the condenser 18 and the radiator 17.
It is considered that most of the air that has passed through the condenser 18 and the radiator 17 flows toward the rear of the engine room 22, and a part of the air flows from the lower portion 17e side of the radiator 17 back to the partition panel 112 side. It is done.

For this reason, for example, if the partition panel 112 is provided on the front side of the capacitor 18 in the vehicle body, air returned from the lower portion 17e side of the radiator 17 to the partition panel 112 side may flow into the space 39 between the capacitor 18 and the radiator 17. It is done.
When the air returned from the lower portion 17e side of the radiator 17 flows into the space 39, it is difficult to ensure the cooling performance of the condenser 18 and the radiator 17.

On the other hand, if the partition panel 112 is provided on the rear side of the radiator 17 in the vehicle body, the partition panel 112 is too far away from the capacitor 18 on the rear side of the vehicle body.
Therefore, it is difficult to guide the air introduced from the grill opening 105 toward the space 38 to the condenser 18 side by the partition panel 112, and it becomes difficult to ensure the cooling performance of the condenser 18 and the radiator 17.

Therefore, the partition panel 112 (partition member 21) is provided between the capacitor 18 and the radiator 17.
Therefore, the air returned from the lower portion 17e side of the radiator 17 to the partition panel 112 side is prevented from flowing into the space 39 between the condenser 18 and the radiator 17, and further, the air introduced from the grill opening 105 is separated by the partition panel 112. It can be led to the capacitor 18 side.
Thereby, the cooling performance of the capacitor | condenser 18 and the radiator 17 is securable.

As shown in FIGS. 10 and 12, a plurality of reinforcing ribs 113 are provided at predetermined intervals in the vehicle width direction, and are formed in a substantially triangular shape with a bottom side 113a, a vertical side 113b, and an inclined side 113c.
The bottom side 113a is a side extending from the front end 111b to the rear end 111a of the mounting seat 111 toward the rear of the vehicle body.
The vertical side 113b is a side that extends upward from the rear end 111a of the mounting seat 111 to the upper end 112a of the partition panel 112.
The inclined side 113c is a side extending downwardly from the upper end 112a of the partition panel 112 to the front end 111b of the mounting seat 111.

By connecting the partition panel 112 and the mounting seat 111 with the reinforcing rib 113, the partition panel 112 can be reinforced with the reinforcing rib 113 and the rigidity (strength) of the partition panel 112 can be increased.
Thereby, it is possible to prevent the partition panel 112 from being inclined (falling down) to the rear of the vehicle body by the air guided from the grill opening 105 during traveling of the vehicle.

Further, by forming the reinforcing rib 113 in a substantially triangular shape, the side facing the lower portion 18c of the capacitor 18 can be formed on the inclined side 113c.
Therefore, the inclined side 113c is greatly separated downward from the lower portion 18c of the capacitor 18, and a large distance H1 between the inclined side 113c and the lower portion 18c of the capacitor 18 can be secured.
Further, the partition panel 112 has an upper end portion 112 a (specifically, a protruding piece 114) disposed below the lower portion 18 c of the capacitor 18 by a distance H2.

Here, the upper end portion 112a (the overhanging piece 114) of the partition panel 112 is provided between the capacitor 18 and the radiator 17 in the longitudinal direction of the vehicle body.
That is, the upper end portion 112a (the overhanging piece 114) is disposed at a position (offset position) away from the cooling system component 16 in the front-rear direction of the vehicle body.
Therefore, it is possible to prevent the condenser 18 and the radiator 17 from interfering with the upper end portion 112a (the overhanging piece 114) when the cooling system component 16 (the condenser 18 and the radiator 17) vibrates in the vertical direction due to the traveling vibration of the vehicle.

Furthermore, by forming the reinforcing rib 113 in a substantially triangular shape, a large distance H1 between the inclined side 113c and the lower portion 18c of the capacitor 18 is ensured.
Therefore, it is possible to prevent the condenser 18 and the radiator 17 from interfering with the inclined side 113c (the partition wall member 21) when the cooling system component 16 (the condenser 18 and the radiator 17) vibrates in the vertical direction due to the traveling vibration of the vehicle.

  As described above, when the cooling system component 16 vibrates in the vertical direction, the cooling system component 16 prevents the cooling system component 16 from interfering with the upper end portion 112a (the overhanging piece 114) and the inclined side 113c. Interference with 21 can be prevented.

The projecting piece 114 projects substantially horizontally from the upper end 112a of the partition panel 112 toward the radiator 17 at the rear of the vehicle body.
By providing the protruding piece 114 at the upper end portion 112a of the partition panel 112, the rigidity (strength) of the partition panel 112 can be further increased.

Here, the air guided from the grill opening 105 during traveling of the vehicle passes through the condenser 18 and the radiator 17, and then a part of the air flows from the lower portion 17e side of the radiator 17 to the partition panel 112 side. Conceivable.
The air that has flowed to the partition panel 112 side may get over the upper end portion 112a of the partition panel 112 and return (recirculate) to the front of the partition panel 112.

Therefore, the projecting piece 114 is provided on the upper end portion 112 a of the partition panel 112.
By providing the protruding piece 114 at the upper end 112a, the air returned to the partition panel 112 side by the protruding piece 114 gets over the upper end 112a and is returned to the front of the partition panel 112 (recirculation). Can be prevented.

Next, a manufacturing method (assembly procedure) of the vehicle body front structure 10 will be described with reference to FIGS.
As shown in FIG. 13A, the upper spring member 67 and the second washer 68 are fitted to the upper fastening bolt 65 of one upper fastening means 43.
In this state, the upper fastening bolt 65 is passed through the slit 63 on one side (outside the vehicle body) of the upper moving bracket 42 and screwed to the welding nut 54 on one side (outside the vehicle body) of the upper support bracket 41 as indicated by an arrow A.

Further, the upper spring member 67 and the second washer 68 are fitted to the upper fastening bolt 65 of the other upper fastening means 43.

Are screwed together as shown by arrow B.

  As shown in FIG. 13B, an upper moving bracket 42 is fastened to the upper support bracket 41 so as to be movable rearward of the vehicle body by a pair of upper fastening means 43.

As shown in FIG. 14A, the lower spring member 93 and the second washer 94 are fitted to the lower fastening bolt 91 of one lower fastening means 73.
In this state, the lower fastening bolt 91 is passed through the slot hole 87 of the lower moving bracket 72 and screwed to the welding nut 78 on one side (outside the vehicle body) of the lower support bracket 71 as indicated by an arrow C.

Further, the lower spring member 93 and the second washer 94 are fitted to the lower fastening bolt 91 of the other lower fastening means 73.
In this state, the lower fastening bolt 91 is passed through the slit 86 of the lower moving bracket 72 and screwed to the welding nut 78 on the other side (vehicle body inner side (vehicle body center side)) of the lower support bracket 71 as indicated by an arrow D.

  As shown in FIG. 14 (b), the lower moving bracket 72 is fastened to the lower support bracket 71 movably to the rear of the vehicle body by a pair of upper fastening means 73.

As shown in FIG. 15 (a), the upper left bracket 16 a (see FIGS. 2 and 3) of the cooling system component 16 is supported by the upper moving bracket 42 in a state where the upper moving bracket 42 is fastened to the upper support bracket 41.
Further, the lower left bracket 16c (see FIG. 2) of the cooling system component 16 is supported by the lower moving bracket 72 in a state where the lower moving bracket 72 is fastened to the lower support bracket 71.

In a state where the upper left portion 16 a of the cooling system component 16 is supported by the upper moving bracket 42, the bolts 51 are inserted into the pair of mounting holes 45 a of the upper support bracket 41.
The pair of bolts 51 inserted are screwed to the welding nuts 52 of the upper beam portion 33 (front wall 15b) as indicated by arrows E.

Further, in a state where the lower left portion 16 c (see FIG. 2) of the cooling system component 16 is supported by the lower moving bracket 72, the bolts 75 are respectively inserted into the mounting holes 71 a at the four corners of the lower support bracket 71.
Then, the four inserted bolts 75 are screwed to the welding nut 76 of the lower beam portion 32 (upper portion 32b) as indicated by an arrow F.

As shown in FIG. 15 (b), the upper support bracket 41 is attached to the upper beam portion 33 (front wall 15 b) with a pair of bolts 51.
Thereby, the upper left part 16a (refer FIG. 2, FIG. 3) of the cooling system component 16 is provided in the upper beam part 33 (front wall 15b) via the upper left support mechanism 35 so that a movement rearward is possible.

Further, the lower support bracket 71 is attached to the lower beam portion 32 (upper portion 32b) with four bolts 75.
Thereby, the lower left part 16c (refer FIG. 2) of the cooling system component 16 is provided in the lower beam part 32 (upper part 32b) via the lower left support mechanism 36 so that a movement to the back of a vehicle body is possible.

As described above, the upper moving bracket 42 is fastened to the upper support bracket 41 by the pair of upper fastening means 43 before the upper support bracket 41 is attached to the upper beam portion 33.
Therefore, the fastening load (that is, “extraction load”) when the upper moving bracket 42 is fastened to the upper support bracket 41 by the pair of upper fastening means 43 can be suitably adjusted.

Similarly, before attaching the lower support bracket 71 to the lower beam portion 32, the lower moving bracket 72 is fastened to the lower support bracket 71 by a pair of lower fastening means 73.
Therefore, the fastening load (that is, “moving load”) when the lower moving bracket 72 is fastened to the lower support bracket 71 by the pair of lower fastening means 73 can be suitably adjusted.

Thus, by suitably adjusting the fastening loads of the upper and lower fastening means 43, 73, the fastening load can be easily managed and the performance quality can be kept good.
Therefore, the cooling system component 16 can be easily assembled to the front bulkhead 15 via the upper left support mechanism 35 and the lower left support mechanism 36.

Next, an example in which the left half of the cooling system component 16 is moved rearward when the obstacle 98 collides lightly (offset collision) with the left front portion of the vehicle body front structure 10 will be described with reference to FIGS. To do.
As shown in FIGS. 16A and 16B, when the obstacle 98 collides lightly with the left front portion of the vehicle body front structure 10, the upper abutment portion 57 (front end portion 57a) of the upper left support mechanism 35 is impacted. The load F1 is transmitted as shown by the arrow.
At the same time, the impact load F2 is transmitted to the lower contact portion 82 (front end portion 82b) of the lower left support mechanism 36 as indicated by an arrow.

Here, as shown in FIG. 17A, the pair of slits 63 of the upper moving bracket 42 are opened toward the front of the vehicle body (see also FIG. 17B).
The upper spring member 67 is compressed by the upper fastening bolt 65 penetrating the slit 63. Therefore, the upper moving bracket 42 is fastened to the upper support bracket 41 by the pair of upper fastening means 43.
As a result, the impact load F1 is transmitted to the front end portion 57a of the upper moving bracket 42, whereby the upper moving bracket 42 moves (slides) as indicated by an arrow G toward the rear of the vehicle body.

  As shown in FIG. 17B, the upper moving bracket 42 is moved rearward to remove one (outside the vehicle body) slit 63 from one upper fastening bolt 65 and from the other upper fastening bolt 65 to the other. The slit 63 (inside the vehicle body (vehicle center side)) can be removed.

Here, the cooling fan 17d of the radiator 17 is rotating.
Therefore, the air flowing in from the grill opening 105 as indicated by arrows I _a and I _b can be guided to the condenser 18 and the radiator 17 as indicated by arrows J _a and J _b .

Here, the partition panel 112 (partition member 21) is provided in the space 38 between the center lower portion 16 d of the cooling system component 16 and the lower beam portion 32.
Therefore, air flowing as shown by arrow I _c from the grille opening portion 105 can be prevented from flowing into the space 38 in the wall panel 112.
Thus, the inlet air as shown by arrow _{I c} from the grille opening portion 105 can be guided as shown by arrow _{J c} in the capacitor 18 and the radiator 17 by the partition panel 112.

Here, as shown in FIG. 12, the rigidity (strength) of the partition panel 112 is enhanced by connecting the partition panel 112 and the mounting seat 111 with the reinforcing rib 113.
Thus, wall panel 112 tilts the rear of the vehicle body in the air flowing as shown by arrow I _c from the grille opening portion 105 (collapses) can be prevented.
Thus, the air flowing as shown by arrow I _c from the grille opening portion 105, the condenser 18 and the radiator 17 by the partition panel 112 can be reliably guided to as arrow J _c.

As described above, all the air guided into the vehicle as indicated by the arrows I _a , I _b , and I _c can be efficiently guided and passed through the condenser 18 and the radiator 17 as indicated by the arrows J _a , J _b , and J _c. it can.

Can be prevented.

In addition, by forming the reinforcing rib 113 in a substantially triangular shape, the inclined side 113 c facing the lower portion 18 c of the capacitor 18 can be largely separated downward from the lower portion 18 c of the capacitor 18.
Therefore, a large distance H1 between the inclined side 113c and the lower portion 18c of the capacitor 18 can be secured.
This can prevent the condenser 18 and the radiator 17 from interfering with the inclined side 113c (the partition wall member 21) when the cooling system component 16 (the condenser 18 and the radiator 17) vibrates in the vertical direction due to the running vibration of the vehicle.

Further, the partition panel 112 is arranged away from the capacitor 18 and the radiator 17 in the longitudinal direction of the vehicle body.
Therefore, when the cooling system component 16 (the condenser 18 and the radiator 17) swings (vibrates) in the front-rear direction when the vehicle is accelerated or stopped, the cooling system component 16 that swings (vibrates) in the front-rear direction becomes the partition panel. Interference with 112 can be prevented.
