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 includes a fuel pump, a pump case, a cap, an O-ring, and a connection assembly. The pump case includes a case main body configured to receive the fuel pump and a discharge port connector. The cap includes a suction port connector. The O-ring is interposed between a fuel discharge port of the fuel pump and discharge port connector. The connection assembly includes a plurality of engagement projections and a plurality of engagement pieces configured to mate and engage with the engagement projections. The fuel discharge port of the fuel pump is configured to reach the O-ring coupled to the discharge port connector of the pump case simultaneous with the engagement between the engagement projections and the engagement pieces when the fuel suction port of the fuel pump and the suction port connector of the cap are connected together.

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.

摘要： A fuel tank unit includes a lid member configured to close an opening formed on a fuel tank. The fuel tank also includes an upper unit attached to the lid member and including a combination valve device configured to be introduced into the fuel tank via the opening formed on the fuel tank and configured to function as an evaporated fuel control valve and a full limit valve. The lid member includes a cylindrical protective case configured to protect the combination valve device of the upper unit when the combination valve device is introduced into the fuel tank via the opening. The protective case is configured to entirely enclose an outer circumferential surface of the combination valve device with a space therebetween.
