周知のように、最近の自動車には、車体の軽量化や形状

要とするばかりでなく、肉厚増加のために燃料タンクの
重役が増加し、樹脂製としての利点が失なわれる。As is well known, resin fuel tanks are attracting attention in recent automobiles from the viewpoint of reducing the weight of the vehicle body and allowing free change in shape. However, if a resin fuel tank is mounted below the vehicle floor panel, there is a risk of it catching fire in the event of a roadside fire or being destroyed by flying stones. For this reason, conventionally, the wall thickness of the resin fuel tank mounted at the bottom of the rear floor panel has been increased to prevent the risk of ignition or destruction, but such measures require a large blow molding machine. Not only that, but the increased wall thickness increases the weight of the fuel tank, and the advantage of being made of resin is lost.
本発明は、以上に述べたような樹脂製燃料タンクの現状
に鑑み、路上火災やはね石から燃料タンクを充分に保護

を提案するものである。In view of the current state of resin fuel tanks as described above, the present invention aims to provide a structure that can sufficiently protect the fuel tank from roadside fires and flying stones, and the present invention aims to provide a structure that can sufficiently protect the fuel tank from roadside fires and flying stones. The present invention proposes that a partial cup-shaped protector be mounted independently on the vehicle body while floating above the fuel tank.
以下、図面について本発明の実施例の詳細を説明する。Embodiments of the invention will now be described in detail with reference to the drawings.

パネル１に固定してある。FIG. 1 is a perspective view of the protective structure of the present invention as seen from below at the rear of the automobile, and shows that the lower part of the rear floor panel L, that is, the rear side members 2A and 2B, is formed with a heat-resistant resin into a flat rectangular shape by blow molding. The fuel tank 3 is fixed to the rear floor panel 1 using a band 4 and bolts 5.

しである。各プロテクタ６Ａ。The left and right sides >1A8a and 8b of the fuel tank 3 are partially covered by cup-shaped protectors 6A and 6B according to the present invention. That is, these protectors 6A,
6B is formed into a cup shape with a metal plate to cover the left and right bottom surfaces and lower side surfaces of the fuel tank 8 when separated from the fuel tank 8, and the leg pieces 6a of each protector 6A, 6B.
is independently fixed to the rear floor panel 1 with bolts 7. Each protector 6A.

を確実如している。6B has spacers 8 fixed at multiple locations on their inner surfaces, and by applying these spacers 8 to the surface of the fuel tank 3, the fuel tank 3 and the protector 6 are separated.
This prevents direct contact between A and 6B and ensures support for the fuel tank 8.

たｆまになることがない。The protective structure according to the present invention has the above-mentioned configuration, and there is a gap between the fuel tank 3 and the protectors 6A and 6B, and the central part of the fuel tank 3 is exposed to open air 1 (so that the fuel tank 3 is exposed to air). Ventilation cooling is carried out to prevent paper lock and water leakage from accumulating on the protector for a long period of time.

The fuel tank 3 is surrounded by flames (as shown in the figure).
The left and right ends 8a, 1 (b) of the fuel tank 8, which have a high flame temperature, are protected by the protectors 6A and 6B and will not catch fire.On the other hand, stones thrown up by the tires 9 are protected by the protectors 6.
A. Since it hits 6BVC, the protectors 6A and 6B will only be deformed.・Fuel tank: There is no danger to the sea urchin.
勿論、本発明によるプロテクタ６Ａ。Of course, the protector 6A according to the invention.

Needless to say, the fan as a whole becomes lighter than when the fuel tank 3 is made thicker.
