By the way, in the above-mentioned conventional technology, the lower surface side of the filter 5 is constantly pressed onto the inclined surface 1A of the fuel tank 1 by the respective parts 6C, 6D of the spring 6, etc., and the filter 5 made of resin fibers such as nylon is Since the lower surface side is sandwiched between the metal spring 6 and the fuel tank 1, the filter 5, etc. may be damaged by vibrations of the car, etc.
When the filter 5 is displaced relative to the inclined surface 1A of the fuel tank 1, the lower surface side of the filter 5 is moved by the spring 6.
This has the disadvantage that there is strong frictional contact with the parts, which tends to cause local wear.

ある。 In addition, welding spatters from seam welds, welds of buttful plates, etc. may remain in the fuel tank 1 as iron particles or iron powder 7 (hereinafter referred to as iron powder 7). Iron powder 7 is, for example, 30~
Since they are formed with a very small particle size of about 50 μm, it is difficult to remove them by cleaning the fuel tank 1, etc., and it is also difficult to remove them by cleaning the fuel tank 1 or by stirring the fuel with the fuel pump 2 or by vibrations of the car. It also gradually peels off from each of the welded parts and mixes into the fuel.
These iron powders 7 pass through the filter 5 made of a mesh of about 70 μm and are sucked into the fuel pump 2 from the suction port 4C of the body 4, which has the drawback of damaging the turbine etc. of each fuel pump 2. be.
さらに、これらの鉄粉類７はフイルタ５とスプ

The features of the configuration adopted by the present invention in order to solve the above-mentioned problems include: a bracket that attaches the filter expansion member to the body using a resin material;
It is formed from a pair of left and right plates that are spaced from the bracket in the left-right direction and extend in the length direction of the filter, each plate having a wavy shape having a bulge that expands the filter upward and downward. The corrugated bulges of each plate absorb iron powder that has flowed into the filter from the fuel tank and prevent these iron powder from entering the fuel pump. This is because a magnet is installed.

With the above configuration, the filter expansion member made of resin material can elastically deform each wave-shaped plate body in response to vibrations of the automobile, etc., and at this time, the lower surface side of the filter is strongly pressed against the bottom surface of the fuel tank. In addition, the filter can be held in an expanded state by the bulging portion of each plate, and the filter can be prevented from shrinking and having a small excess area.

These iron powders can be adsorbed and captured within the filter, and these iron powders can be prevented from accumulating between the lower surface of the filter and the bottom of the fuel tank.
