持するようにしている。Prior Art As is well known, fuel tanks for automobiles have internal functional parts such as a fuel gauge unit, remaining amount detector, and feed pump (in the case of an in-tank pump type) arranged inside the tank.
Generally, in order to arrange these internal functional parts, a stay is fixed to a lid that closes an opening formed in the upper wall of the tank, and the various functional parts mentioned above are attached to this stay and suspended. There is.

場合、上、下シェルの成形誤差や、リッド、ステイの成
形１組付誤差等の集積によって、各種機能部品のタンク
内配設位置を設計通りに一定に決めることは難かしい。When various functional parts are suspended and supported on a stay fixed to one solid in this way, since the lid is fixed to the top wall of the tank, the stay that is suspended from the top wall of the tank with this tank top wall as a reference will end up being suspended. The various functional parts mentioned above will be attached to. The tank body is constructed by butting and joining an upper shell and a lower shell, and therefore, when various functional parts are installed using the tank upper wall as a reference as described above, molding errors of the upper and lower shells, Due to the accumulation of molding and assembly errors of the lid and stay, it is difficult to uniformly determine the positions of various functional parts in the tank as designed.
また、これら機能部品のタンク内配役位置が設計通りに
決まったとしても、タンク底壁が路面干渉等により変形
した場合には対処−「ることはできない。Furthermore, even if the positions of these functional parts in the tank are determined as designed, it is not possible to deal with it if the bottom wall of the tank is deformed due to interference with the road surface, etc.

ドポンプの支持安定性に欠けて実用に適さない問題があ
る。Therefore, as in, for example, Japanese Utility Model Application Publications No. 52-30154 and No. 58-119419, functional parts are attached so as to be slidable up and down, and the functional parts are urged downward by a spring member. A functional component is attached to the end of the suction pipe, and the functional component is forced downward by a pressure means at the end of the suction pipe, so that the functional component is grounded to the bottom wall of the tank, and the mounting reference is the bottom wall of the tank. Proposed. However, when various functional parts are attached to a suction pipe, the suction pipe does not only have the function of sucking fuel, but also has to function as a support member, so it is necessary to increase the pipe diameter or the pipe thickness. There is a problem that the heavy pot requires a large size, which increases the cost, and especially when an ink tank pump type specification is used, there is a problem that the feed pump, which is heavy, lacks support stability and is not suitable for practical use.

う実用上多大な効果を有する。Effects of the Invention As described above, according to the present invention, the fuel gauge unit 2,
For fuel gauges and in-tank pump type tanks, functional parts inside the tank such as the feed pump can always be mounted at a constant height from the tank bottom wall using the tank bottom wall as a reference. The unit and remaining amount detector can accurately detect the amount of change in fuel in the tank, and the suction ports of the feed pump, suction pipe, etc. are placed as close as possible to the bottom wall of the tank. This has the advantage that the amount of unsucked fuel can be significantly reduced. Since these internal functional parts are mounted across the tank top wall and the tank bottom wall, they have excellent mounting stability and can be reliably mounted, which is a great practical effect.
