A pair of left and right stays 16 are welded or integrally formed on the left and right side edges of the heat shield plate 15, so that the left and right stays 16 are fixed on the vehicle body 5. That is, the heat shield plate 15 forms a part of the left and right stays 16.

Attachments 17 are fixed to the lower portions of the left and right stays 16 (substantially the heat shield plates 15), and a pair of left and right middle brackets 18 are fixed to the middle portions, respectively. Mounting tool 17
One leg of a pedestal 20 for receiving the bottom of the fuel tank 14 via a cushion material 19 is bolted to the holder. The other leg of the pedestal 20 is connected to a fixture 21, and this fixture 21 is fixed to the vehicle body 5. The left and right middle brackets 18 are bolted to the vertically oriented midway portions of the vertical flange portion 14a of the fuel tank 14.

L-shaped metal fittings 23 are welded to the upper rear surfaces of the pair of left and right stays 16, and both ends of a presser member 24 made of a band plate are fixed to the left and right metal fittings 23 with bolts 25 and installed thereon. The holding member 24 is disposed above the fuel tank 14 and can hold the fuel tank 14 from above toward the pedestal 20 side via the cushion material 26, and exerts holding force by fastening the bolt 25.

One or more upper brackets 27 are provided rearwardly in the middle of the holding member 24, and the rear portions of the upper brackets 27 are connected with bolts 28 to the upper portions of the vertical flange portions 14a. The upper bracket 27 is formed of a strip plate;
(or the flange portion 14a) is formed with an elongated hole 29 in the vertical direction for passing through the bolt 28, and the holding member 24
The upper bracket 27 is designed to be able to be connected even if it moves up and down slightly to hold down the fuel tank 14. The presser member 24 and the pedestal 20 are spaced apart from the vertical flange portion 14a of the fuel tank 14 in one front and back side (front), and are in contact with the outer surface of the fuel tank 14 so as to press in the front and back directions and the rest. Prevents vertical vibration.
