摘要： A fuel supply device includes a flange unit and a pump unit. The flange unit includes a flange main body for closing an opening formed in an upper wall of a fuel tank. The pump unit includes a joint member that is connected to the flange main body so that both components may be movable relative to each other in the vertical direction. The interval in the vertical direction between the flange main body and the joint member is restricted from going below a minimum vertical interval. The minimum interval occurs when a stand-off portion provided as part of the flange main body and a connecting plate portion provided as part of the joint member come into mutual contact with each other and abut each other in the vertical direction.

摘要： A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member movably coupled to the flange unit. The joint member is configured to move in an upward/downward direction relative to the flange unit. Two side tubular portions extend from the flange unit in the upward/downward direction and are positioned side-by-side. Column portions extend in the upward/downward direction from the joint member. The column portions are moveably disposed in the side tubular portions. The column portions are configured to move in the upward/downward direction relative to the side tubular portions. The side tubular portions are connected to each other via a rear side wall and a front side wall of a center tubular portion disposed between the side tubular portions.

摘要： A fuel supply device is insertable into a fuel tank through an opening formed in an upper wall of the fuel tank in an insertion direction. The fuel supply device includes a flange unit and a pump unit coupled to the flange unit. The pump unit includes a guide member extending in the insertion direction. The guide member is configured to abut on an opening periphery so as to guide the pump unit when the pump unit is inserted into the fuel tank. A guide surface of the guide member includes a concave surface.

摘要： When a fuel tank is inclined at a negative slope and tilted to the right side, it may be tilted such that a position of a mesh member is relatively higher than a position of a vapor outlet of a vapor outlet passage. In this case, air may enter into a leak passage from an outlet port such that interfacial tension is generated in the mesh member. The interface between fuel and air is present at the mesh member, and the interfacial tension generated at the interface serves to prevent air from entering into a discharge pipe.

摘要： A fuel tank cover (150) is provided with a flange unit (22) closing an opening of a fuel tank, and a joint member (24) configured to be connected to the flange unit (22) movably in the upward/downward direction. The flange unit (22) includes a side tubular portion (43) extending in the upward/downward direction. The joint member (24) includes a columnar portion (160) extending in the upward/downward direction. The columnar portion (160) is inserted into the side tubular portion (43) movably in the upward/downward direction. A metal retainer (162) is provided to cover an outer circumferential surface of the columnar portion (160).

摘要： A flange main body as a cover member for a fuel tank includes a cover plate for closing an opening of the fuel tank, an accommodating tubular portion formed as part of the cover plate so as to extend through the plate in a plate thickness direction, and a rib formed at the cover plate. The accommodating tubular portion and the rib are formed to be non-contiguous.

摘要： A fuel supply device includes a flange unit configured to be attached to an upper wall of a fuel tank to close an opening of the fuel tank, a pump unit configured to be disposed within the fuel tank, and a coupling mechanism moveably coupling the pump unit to the flange unit in a vertically slidable manner. The coupling mechanism includes a fixed-side rail member having a rail portion extending vertically from the flange unit, and a movable-side rail member having a channel-groove shaped rail groove extending from the pump unit. The channel-groove shaped rail groove is slidably engaged with the rail portion of the fixed-side rail member. A recess having a semi-circular cross section is formed at a corner of the rail groove of the movable-side rail member.

摘要： A fuel filter device includes a bag-shaped filter member filtering fuel that is drawn into a fuel pump, an inner frame member retaining the filter member in an expanded state, and a mounting member connected to the inner frame member and serving to communicate an internal space of the filter member with an outside. A valve chamber is defined by the inner frame member and the mounting member, and a check valve serving to prevent backflow of fuel is disposed in the valve chamber. The check valve includes a flat-plate shaped valve body having elasticity. The check valve opens against its weight when the fuel pump is operated, and the check valve closes due to its weight when the operation of the fuel pump is stopped.
