Therefore, from the load of shock absorber 126 inputs, via vertical the first reinforcement 156 established of the vehicle front side at seat surface 132 and via vertical the second reinforcement 158 established of the vehicle rear-side at seat surface 132, transmit and be dispersed to separation side plate 140 and dividing plate 138.Adopt this structure can effectively transmit and disperse from the load of shock absorber 126 inputs, can also in the situation that suppressing vehicle weight increase, guarantee enough durabilitys (rigidity).
As shown in Figure 3, the first reinforcement 156 is connected with the 3rd reinforcement 160 of the second reinforcement 158 by seat surface 132 tops.The upper end of the 3rd reinforcement 160 is engaged to the downside of separating side member 146.Note, the lower end of the 3rd reinforcement 160 stops under the state that does not extend to rear wheel cover 130.The introducing of the 3rd reinforcement 160 can strengthen the first reinforcement 156 and the second reinforcement 158.
This can prevent that central role from being transmit and disperse from the first reinforcement 156 and second reinforcement 158 appearance damage and the fractures of the load of coil spring 124 and shock absorber 126 inputs.In addition, owing to being passed to the load of the first reinforcement 156, by the 3rd reinforcement 160, be passed and be dispersed to the second reinforcement 158, the load that is passed to the second reinforcement 158 is passed and is dispersed to the first reinforcement 156 by the 3rd reinforcement 160, also plays the effect that can more effectively transmit and disperse load.
As shown in Figure 1, separate side plate 140 and comprise the peristome 164 forming near vehicle-width direction outside.In addition, as shown in Figure 8, between the first reinforcement 156 and rear side coaming plate 148, the second reinforcement 158 and and rear side coaming plate 148 between and between the 3rd reinforcement 160 and rear side coaming plate 148, be formed with space 174.In other words, in the present embodiment, the first reinforcement 156, the second reinforcement 158 and the 3rd reinforcement 160 do not extend to vehicle right flank.
Adopt this structure will such as wire harness 166 cables such as grade, pass the peristome 164 of separating side plate, and cable configurations is become to pass between rear side coaming plate 148 and the first reinforcement 156, the second reinforcement 158 and the 3rd reinforcement 160.In other words, wire harness 166 grades can be disposed to vehicle right flank.This has eliminated wire harness 166 grades has been fixed on to the demand on rear floor panel 102, has therefore eliminated the demand that for the parts (clip) of fixed beam 166 grades, rear floor panel 102 is arranged hole in order to arrange.This can be avoided leaking and being avoided the deteriorated of NVH performance (noise, vibration and stationary performance).
Although above with reference to the accompanying drawings of the preferred embodiment of the present invention, should be appreciated that and the invention is not restricted to the above embodiment illustrating.It is evident that for a person skilled in the art, in the scope of the present invention limiting at appended claims, can make various modification and variation, these modification and curvedization should be understood to be included in technical scope of the present invention.
