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： 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 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 motor includes a stator and a rotor having a rotor shaft. The motor includes a bearing having an inner ring and an outer ring that are configured to rotate relative to each other. The inner ring is supported by the rotor shaft. The motor also includes a holder that supports the outer ring. The holder is clearance-fitted to a retainer on a stator side. A rotation prevention apparatus configured to prevent the rotation of the holder is positioned between the holder and a stopper member on the stator side.

摘要： A fuel supply device includes a sub-tank, a fuel pump, a transfer jet pump, a reduction valve, and a partition wall. The sub-tank is disposed within the fuel tank and forms a container configured to store fuel. The fuel pump is disposed in the sub-tank and is configured to pump fuel from the sub-tank. The transfer jet pump is configured to pump fuel from the fuel tank into the sub-tank. The reduction valve generates heat during operation. The partition wall divides an interior of the sub-tank into a first chamber and a second chamber. The fuel pump is disposed in the first chamber. Fuel passing through the reduction valve is discharged into the second chamber.

摘要： A fuel supply device has a cover member which is attached to an opening of a fuel tank, a pump unit comprising a pump, and a connecting portion configured to connect the cover member and the pump unit. A connecting shaft which is formed to one of the two connected members of the connecting portion is inserted into a connecting hole which is formed to the other of the two such that the pump unit is connected to be relatively movable to the connecting portion. The pump unit includes an upper base on which the pump is placed, and a lower base which contacts to the fuel tank. The upper base and the lower base are coupled through attachments whereby an engagement portion of the upper base is fitted into a recessed portion formed on the side of the lower base. The recessed portion has a pair of planes opposing to each other and oriented toward a bottom surface of the lower base from a predetermined position. The recessed portion is further configured such that an interval between a pair of the planes is gradually increased toward the bottom surface.
