Abstract

A fuel supply device is obtained in which joint strength can be maintained in a joint portion of plural filter members configuring a fuel filter. A fuel filter with an overall bag shape is configured by welding together an upper face filter cloth a lower face filter cloth of the fuel filter at a welded portion. A sub tank upper side member and a sub tank lower side member nip the upper face filter cloth and the lower face filter cloth at a nipping position that is at a different position from the welded portion.

First claim

The invention claimed is:

1. A fuel supply device comprising:
a fuel tank body that stores fuel;
a fuel filter that is provided inside the fuel tank body and formed in an overall bag shape with a plurality of sheets of filter members superimposed on each other and joined together by a joint portion so as to permit passage of the fuel and restrict passage of foreign matter in the fuel, wherein the joint portion is a part of the fuel filter;
a nipping member that nips the plurality of sheets of filter members at a nipping position that is a different position from the joint portion;
a separation maintaining member that is disposed between the plurality of sheets of filter members and that maintains a separation between the filter members;
a feed-out device that feeds out fuel from inside the fuel filter to the fuel tank body exterior; and
a storage member that is provided on the fuel filter and stores the fuel,
wherein the feed-out device is supported over the storage member by a bracket and oriented horizontally.

2. The fuel supply device of claim 1 , wherein the storage member includes a bottom plate portion below the fuel filter and that the plural insertion through holes are formed penetrating the bottom plate portion.

3. The fuel supply device of claim 1 , wherein:
the fuel filter is formed in a flattened bag shape by employing the plurality of sheets of filter members disposed from top to bottom, and joining the plurality of sheets of filter members together with the joint portion set at an outer peripheral portion of the filter members; and
the nipping member nips the plurality of sheets of filter members in an up-down direction at the nipping position.

4. The fuel supply device of claim 3 , wherein the separation maintaining member is disposed so as to maintain the separation between the plurality of sheets of filter members in the up-down direction.

5. The fuel supply device of claim 1 , wherein the nipping member comprises:
two nipping tabs that are rotatably coupled to each other by a hinge portion; and
a nipping maintaining member that maintains a nipping state of the plurality of sheets of filter members by the two nipping tabs.

6. The fuel supply device of claim 1 , wherein the joint portion lacks any contact with the nipping member.

7. The fuel supply device of claim 1 , wherein the joint portion is a welded portion.

8. A fuel supply device comprising:
a fuel filter that is formed in an overall bag shape with a plurality of sheets of filter members superimposed on each other and joined together by a joint portion so as to permit passage of the fuel and restrict passage of foreign matter in the fuel, wherein the joint portion a part of the fuel filter;
a nipping member that nips the plurality of sheets of filter members at a nipping position that is a different position from the joint portion;
a separation maintaining member that is disposed between the plurality of sheets of filter members and that maintains a separation between the filter members;
a feed-out device that feeds out fuel from inside the fuel filter; and
a storage member that is provided on the fuel filter and stores the fuel,
wherein the feed-out device is supported over the storage member and oriented horizontally.
