Abstract

Le problème posé par l'invention consiste en ce que, lorsqu'un support de réservoir pour monter une partie arrière d'un réservoir de carburant sur une carrosserie de véhicule doit être prévu, si le support de réservoir est soudé uniquement à une plaque de base, une forte contrainte est facilement concentrée sur cette partie soudée et ainsi, la présente invention aborde le problème de permettre une dispersion de contrainte qui est appliquée au support de réservoir. La solution selon l'invention porte sur une partie arrière d'un réservoir de carburant sans bride (13), sur laquelle sont prévus un premier support (20) s'étendant vers l'arrière à partir d'une plaque externe (13a) et un second support (21) s'étendant vers l'arrière à partir d'une plaque de base (13b). Des parties arrière respectivement du premier support (20) et du second support (21) sont superposées l'une sur l'autre de manière à être intégrées l'une à l'autre, ce qui permet d'obtenir une partie de fixation côté cadre (15a). Dans cet état, le montage sur le côté cadre d'une carrosserie de véhicule est effectué au moyen d'un boulon (16) en un seul point. Une partie avant (30) du premier support (20) est montée sur la surface arrière de la plaque externe (13a) par soudage, et une partie avant (40) du second support (21) est montée sur la surface inférieure de la plaque de base (13b) par soudage. Le poids appliqué depuis le réservoir de carburant (13) sur un support de réservoir (15) est dispersé sur le premier support (20) et le second support (21), la concentration de contrainte qui est appliquée à une partie au niveau de laquelle le support de réservoir (15) est monté sur le réservoir de carburant (13) est donc atténuée.
