A fuel supply device includes a fuel pump, a sub-tank configured to store a fuel, a leakage passage configured to return a part of a pressurized fuel discharged from the fuel pump into the sub-tank, and a fuel filter disposed at a bottom part of the sub-tank. The fuel filter includes a filter member that is configured to filter the fuel to be suctioned into the fuel pump. A downstream end of the leakage passage includes a linear passage part linearly extending from a position above the filter member toward the filter member. The fuel supply device also includes a direction change wall part configured to change the flow direction of the pressurized fuel jetted from the linear passage part so as to prevent the pressurized fuel from directly impacting the filter member.

Fuel supply device

A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member connected to the flange unit. The joint member is movable in an upward/downward direction. The flange unit includes a side tubular portion extending in the upward/downward direction. The joint member includes a support column portion extending in the upward/downward direction. The support column portion is movably disposed in the side tubular portion so as to be movable in the upward/downward direction. The support column portion is connected to the side tubular portion by a snap-fit so as to be movable and suspendable in the upward/downward direction.

Cover for fuel tank

A liquid level detector may include a float; an arm attached to the float and configured to convert a linear motion of the float in an up-and-down direction to a rotary motion; a sensor configured to detect the rotary motion; and a supporting member supporting the arm to be rotatable relative to the sensor. The supporting member may include: a body fixed to the sensor; a holder rotatably attached to the body; and a cover arranged on an opposite side from the body with the holder intervened in between, and covering the holder from the opposite side. The arm may be supported by the supporting member between the holder and the cover.

Liquid level detector

A liquid level detector may comprise an arm attached to a float, a holder fixed to the arm, and a body rotatably supporting the holder. The body may comprise a first rotation regulator and a second rotation regulator. The first rotation regulator may regulate a rotation angle range of the arm to a first range. The second rotation regulator may regulate the rotation angle range of the arm to a second range. The first range and the second range may not overlap each other in a rotation direction of the arm. Each of the plurality of rotation regulators may comprise a pair of stoppers disposed separately from each other in the rotation direction of the arm. At least a part of area between the pair of stoppers of the each of the plurality of rotation regulators may be open to outside of the body.
