うにしてなる燃料タンクの脱落防止構造にある。The gist of the present invention is to focus on a protector that prevents the fuel tank from drying out between the differential gear and the barrel case, and to form a protruding piece extending close to the bottom of the tank mounting portion on the protector. The present invention provides a structure for preventing a fuel tank from falling off, in which a joining flange of the fuel tank is engaged with the protruding piece when the fuel tank falls off.
以下、添付図面に示す実施例に基づいて本発明の詳細な
説明する。Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

を省略する。In this embodiment, a plate-shaped protector 10 for preventing interference between the fuel tank 1 and the differential case 9 is fixed to the front mount member 4f via a bolt 11 and a weld nut 12. is formed with a protruding piece 20 that extends close to the front tank attachment part A, that is, the lower part of the L-shaped bracket 5, and the tip of this protruding piece 20 covers the lower front corner of the fuel tank 1. The bent piece 21 is integrally formed. And, this protector 10 is
After the fuel tank 1 is assembled to the vehicle body, it can be assembled to the front mount member 4f. It should be noted that other components having the same configuration as the conventional one are given the same reference numerals as the conventional one, and a detailed explanation thereof will be omitted here.

完全に防止される。Therefore, according to this embodiment, since the tank mounting portion supporting the front side of the fuel tank 1 and the front lower corner portion of the fuel tank 1 are bent by the protector 10, dirt and debris from the road surface can be removed from the tank. The possibility of the attachment part AK falling directly is reduced, and the possibility of the fuel tank 1 falling off due to rusting of the tank attachment part A is correspondingly reduced. In addition, if the tank mounting part A becomes rusty, the tank mounting part A becomes brittle and the tank mounting part A becomes weak.
However, as shown in Figs. 2 and 3, in such a state, the front side of the fuel tank 1 may fall downward with the rear tank mounting part B as the center of rotation. The front joint flange 2 of the fuel tank 1 comes into contact with the protruding piece 20 of the protector 10, and the lower front corner of the fuel tank 1 comes into contact with the bent piece 21 of the protector 10, causing the fuel tank 1 to fall. Protector 1 on the front side
It is supported by 0. As a result, the situation where the fuel tank 1 falls off until it hits the ground is avoided, and fuel leakage and fire caused by the accident of the fuel tank 1 falling off are completely prevented.

。Furthermore, in this embodiment, if both sides of the protector 100 are extended to cover the sides of the fuel tank 1, the protector 10 can prevent hot air from the exhaust pipe etc. disposed on the sides of the fuel tank 1. It also acts as a heat shield that blocks out the metal.

勿論である。Incidentally, in the above embodiment, the protector 10 is formed by integrally forming the bent piece 21 at the tip of the protruding piece 20, but the above-mentioned bent piece 21 is not necessarily limited to this. The protruding piece 20 alone may be used to prevent the fuel tank 1 from falling off without providing the piece 21 in particular. Further, the mounting structure of the fuel tank 1 is not limited to that shown in the above embodiment, and it goes without saying that the present invention can be applied to a type in which the fuel tank is disposed at the lower part of the vehicle body.

ができる。As explained above, according to the fuel tank fall prevention structure according to the present invention, the protruding piece extending close to the bottom of the tank mounting part is integrated into the protector that prevents interference between the fuel tank and the differential case. Therefore, even if the tank mounting part rusts and the fuel tank falls off from the tank mounting part, the front joint 7 flange of the fuel tank will be locked to the protruding piece of the protector. The front side of the fuel tank is supported by a protector. Therefore, the accident of the fuel tank falling off can be prevented without increasing the number of parts, and it is possible to reliably avoid the accidental leakage of fuel and fire caused by the accident of the fuel tank falling off.
