Problems solved by technology

[0009] However, since the above-mentioned structure includes two parts of the sub-box and the board, it lacks sufficient elasticity in the structure, and the effect of stress dispersion is low, so that there is a load on the sub-box or the board.

Embodiment Construction

[0022] Next, embodiments of the present invention will be described.

[0023] figure 1 is a perspective view of the lower tank 12 constituting the fuel tank 10 according to the present embodiment; figure 2 is a plan view of the lower tank 12 constituting the fuel tank 10; image 3 is a side perspective view of the fuel tank 10; Figure 4 yes figure 2 XX line cross-sectional view; Figure 5 yes figure 2 The YY line sectional view; Figure 6 is a perspective view of the flow suppression unit 32 .

[0024] Such as image 3 As shown, the fuel tank 10 is assembled from a lower tank body 12 constituting the lower half and an upper tank body 14 constituting the upper half.

[0025] Such as figure 1 , figure 2 As shown, the lower box body 12 includes: a bottom wall 16 that is elongated and constitutes the bottom surface of the fuel tank 10; a side wall 18 that rises from the edge of the bottom wall 16 to constitute the side of the fuel tank 10; and a flange 20 , extendi...

Abstract

The present invention provides a fuel tank which comprises a flow restraining unit that restrains the fuel flowing. The flow restraining unit comprises the following components: a central part which has a length and a width relatively to the length direction and width direction of the fuel tank and is provided on a bottom of the fuel tank; and a vertical part which extends from two ends in the length direction of the central part to the upper side of the fuel tank. At least one part at the front end of the vertical part is provided with spaces between two ends of the central part and the outside, and returns to the bottom of the fuel tank.

Description

technical field [0001] The invention relates to a fuel tank. Background technique [0002] The following technical scheme is disclosed in the Japanese Patent Application Publication No. 2004-197733: In order to stably measure the remaining amount of fuel contained in the fuel tank on vehicles such as automobiles under any vehicle running state, a fuel tank with a fuel tank is provided inside the fuel tank. The small-capacity sub-tank connected to the sub-tank detects the height of the float member floating on the liquid surface of the fuel contained in the sub-tank, so as to obtain the remaining amount of fuel according to the detection result. [0003] However, the fuel tanks are manufactured in different sizes according to vehicle models. On the contrary, in order to reduce the cost, the sub-tanks are usually manufactured in the same size and are common. [0004] Therefore, the gap formed between the outer surface of the wall constituting the sub tank and the inner surfac...
