Left side floor side member 3L, right side floor side member 3R, rear cross beam 4 and middle cross beam 5.
As shown in Figure 1, being provided with concave heel slab 6 on rear portion floor 2.The heel slab 6 is for loading conduct
The tote mounting portion of the spare tyre 7 of tote.Fixed spare tyre is bonded at the substantially intermediate position of the inner bottom surface of the heel slab 6
7 bracket 8.
Fig. 2 is the cross-sectional view of the arrow direction of (2)-(2) line in Fig. 1, and Fig. 3 is the top view for indicating heel slab 6.
As shown in Fig. 2, the wheel 7a of spare tyre 7 is fixed on the top of bracket 8 by spare tyre folder 9.
In order to improve the support strength of the rear suspension (not shown) controlled to ensure control stability, rear cross beam 4, which uses, to be cut
Face is the hollow member of hat, also, heel slab (the tote load on rear portion floor 2 is arranged in along vehicle width direction for the rear cross beam 4
Set portion) 6 lower surface, before prominent flange and rear flange be engaged respectively on the lower surface of heel slab 6, behind left end and left side
Stringer 3L connection, right end and right side floor side member 3R connection.
Specifically, in the left part and right part of the vehicle width direction of rear cross beam 4, a left side (not shown) has been respectively fixedly connected with it
The right respective rear section of rear overhang frame member, the position that rear cross beam 4 is fixedly connected with the rear overhang frame member of left and right are to show in Fig. 3
Fixed connection point 101,102 out.To, in front side of rear overhang frame member or so and total four positions of rear side or so,
It is supported between fixed connection point 102 on the right of the fixed connection point 101 and rear side on the rear side left side by rear cross beam 4.It can improve as a result,
The support strength of the rear suspension of left and right.
In addition, being provided with being separated by specified interval with the rear cross beam 4 substantially flat with the rear cross beam 4 in the front of rear cross beam 4
The middle cross beam 5 on capable rear portion floor 2.In the left part and right part of the vehicle width direction of the middle cross beam 5, it has been respectively fixedly connected with
The respective front part of rear overhang frame member of left and right is stated, the position that middle cross beam 5 is fixedly connected with the rear overhang frame member of left and right is Fig. 3
Shown in fixed connection point 103,104.
When vertical view, forming approximate groined type in the component that four fixed connection points 101~104 are fixedly connected (but can also be with
Using the structure for forming approximation X font).
In present embodiment, as shown in Figure 1, rear cross beam 4 is configured as, than the intermediate position of the inner bottom surface of heel slab 6
(that is, junction 11 that bracket 8 is engaged with tote mounting portion) is closer to the front side in vehicle commander direction.In other words, make to bear standby
The bracket 8 of the load of tire 7 is staggered position on vehicle commander direction with rear cross beam 4.The load of spare tyre 7 and vibration as a result, will not 100%
It is born by rear cross beam 4.
In addition, in present embodiment, as shown in Fig. 2, being provided with load in the lower surface of heel slab (tote mounting portion) 6
Junction 11 between bracket 8 and heel slab 6 is connected by lotus transmission member 10, the load transmission member 10 with rear cross beam 4.
The load transmission member 10 can be constituted using the board member of referred to as patch with suitable metal or fibre reinforced plastics etc..
Specifically, as shown in Fig. 2, load transmission member 10 is configured to, from the junction 11 of 8 rear end of bracket
Lower section extends to rear cross beam 4 and forward downward inclination, and the lower surface for the rear cross beam 4 that section is hat is covered.Meanwhile the load
The rear end of transmission member 10 is connect across heel slab 6 with the rear end of bracket 8, the front end of the load transmission member 10 with
The following table face bonding of rear cross beam 4.Thus, by load transmission member 10, the junction 11 of bracket 8 is connected with rear cross beam 4.
Using the above structure, when the vibration etc. in traveling causes spare tyre 7 to vibrate, the vibration is on heel slab 6 from support
The junction 11 of frame 8 is transmitted to rear cross beam 4 via load transmission member 10.Therefore, the joint portion on rear portion floor 2 can be alleviated
Stress collection on position (junction 11, heel slab 6 between heel slab 6 and bracket 8 and the junction between rear cross beam 4)
In, so as to inhibit the deflection of above-mentioned junction.
It does not need to take as a result, and the plate thickness on rear portion floor 2 is increased into such measure, to be avoided that car body weight increases
Add.
As described above, the vehicle rear body structure based on present embodiment, the plate thickness without increasing rear portion floor 2 can also be alleviated
Stress on above-mentioned junction is concentrated.
In addition, the utility model is not limited to above embodiment, various modifications and change can be carried out.
For example, listing the example of spare tyre as tote, but the utility model is not limited in above embodiment
This, tote for example can be audio-frequency amplifier or various electronic control units etc..In this case, it is possible to correspond to tote
Shape, size etc. design the shapes and sizes of bracket.
For example, as shown in Figure 4, bracket 8 is preferably configured to flat by tote 70 biggish for base area
The biggish shape of face area.
In addition, preferably, the form and dimension of design load transmission member 10 is carried out corresponding to the form and dimension of bracket 8.
In addition, showing load transmission member 10 in above embodiment for connecing between the rear end of bracket 8 and heel slab 6
The structure that position 11 is connected with rear cross beam 4 is closed, but load transmission member 10 can also be used the front end of bracket 8 and rear portion bottom
The structure or load transmission member 10 that junction 11 between plate 6 and rear cross beam 4 are connected by the front end of bracket 8 and rear end with
