っている。BACKGROUND OF THE INVENTION As is well known, fuel tanks for automobiles are equipped with functional parts at the tip of the feed pipe such as a fuel strainer and feed pump inside the tank body, as well as internal functional parts such as a fuel gauge unit and a remaining amount detector. In order to accommodate all of these internal functional parts, a feed pipe is passed through and installed in the lid that closes the working hole made in the earthen wall of the tank body, and a stay is fixed to the back of this lid, and each of the above-mentioned parts is attached to this stay. It is designed to be suspended and supported by attaching highly functional parts. The internal functional parts of each pole mentioned above are often placed at positions offset from the center of the tank body in consideration of the influence of fuel drive when the vehicle turns. is not necessarily located on the upper wall of the tank body, depending on the location of the service hole on the vehicle body side, the piping layout connecting the feed pipe fixed to the lid to the fuel supply system, and the harness layout of electrical components such as the fuel gauge unit and remaining amount detector. Usually, it is not established in the most suitable location. For this reason, the feed pipe is
In many cases, a pipe is protruded in a complicated manner so that the tip of the pipe reaches a set position on the back side of the lid in accordance with the lid arrangement position, which varies depending on the specifications. This feed pipe is fixed by welding to the periphery of the boss part that is bent and formed on the back side of the lid, but as mentioned above, if the protruding part of the feed pipe is complicatedly bent, the bent part of the feed pipe This creates a problem that becomes a hindrance and makes welding work extremely difficult. Furthermore, as mentioned above, the bending state of the feed pipe differs depending on the size and specifications, so the lid/feed pipe assembly is a dedicated component and lacks versatility, which is a major factor in increasing costs.

対処することはできない。On the other hand, in addition to this problem, since the functional parts inside each cage are suspended and supported by stays fixed to the lid, these functional parts are installed with the upper wall of the tank body as a reference, so the following problems are required. Causes problems. That is, the tank body is constructed by butting and joining the upper shell and the lower 7 L. Therefore, when various functional parts are installed with the tank upper wall as a reference as described above, the molding of the upper and lower shells is difficult. Due to the accumulation of errors, molding errors of the lid and stay, assembly errors, etc., it is difficult to uniformly determine the placement positions of various internal functional parts in the tank as designed. Further, even if the positions of these functional parts in the tank are determined as designed, it is impossible to deal with the case where the bottom wall of the tank is deformed due to interference with the road surface or the like.

残し量が多くなってしまうという不具合を生じる。As a result, the fuel level height detection by the fuel gauge unit and the remaining amount detection by the remaining amount detector cannot be performed accurately, or the fuel suction port of the feed pump or feed pipe is too far away from the bottom wall of the tank body. As a result, a problem arises in that a large amount of fuel remains unsucked.

まう不利があった。Therefore, as in, for example, Japanese Utility Model Application Publication No. 52-30154 and Japanese Utility Model Application Publication No. 58-119419, it has been proposed that the functional parts inside the tank are urged toward the bottom wall of the tank body by a pressure means. However, in both cases, the lid/feed pipe assembly is a dedicated part, so there is no versatility, and a special biasing mechanism is required.
