A box device includes a box body having a housing portion with an upper opening, and a front movable member and a rear movable member slidably disposed in front and rear directions in the box body for opening and closing the upper opening of the housing portion. The box device further includes a first guide portion engaging the front movable member for guiding the front movable member to slide in the front and rear directions; a second guide portion engaging the rear movable member for guiding the rear movable member to slide in the front and rear directions; and an engaging device for connecting and disconnecting the front movable member and the rear movable member.

A valve device used by being attached to a fuel tank includes a case provided with an airflow valve opening which communicates with the outside of the tank, on an upper portion, and also provided with a fuel inflow section located on a lower side of the airflow valve opening, and a float body housed in the case so as to be vertically movable, and also seated in the airflow valve opening by being elevated by the fuel flowed into the case through the inflow section. In the case, an airflow section which interconnects the inside of the tank and the inside of the case is formed in a higher side than a waterline of the float body at the seating time, and also at the seating time, this airflow section is restricted.

In a vent control valve for a fuel tank, a housing receiving a float assembly therein is provided with a communication hole passed across a wall of the housing, and an opening of the communication hole facing an interior of the housing is directly exposed to an interior of the housing when the float assembly is in a low position and overlaps with a peripheral wall of the float assembly when the float assembly is in a high position. By suitably selecting the size of the communication hole and/or the number thereof, a desired delay in the dropping of the liquid fuel level in the housing following the filling up of the fuel tank can be achieved. Thereby, overfilling of the fuel tank can be avoided. As the float assembly drops to such an extent as to clear the communication hole, the fuel vapor is allowed to flow more freely into the interior of the housing via the communication hole, and this causes an increase in the speed of the float to drop. Thereby, the venting of the fuel tank can be resumed at an appropriately earlier stage following the filled up state of the fuel tank. Thus, the closing and opening of the communication with the exterior of the fuel tank can be accomplished even when the vertical dimension of the housing is relatively small.

A fuel tank connector includes an upper chamber provided with a first communication portion relative to a ventilation flow path; and a lower chamber provided with a third communication portion relative to the upper chamber. A bowl-shaped portion narrowing downward is formed in a bottom portion of the upper chamber, and the third communication portion is formed in a bottom of the bowl-shaped portion. A cover body having a container shape, including a top portion and a side portion and opening at a lower face is supported directly above the third communication portion with a ventilation interval between the open edge and the third communication portion.

A fuel tank plumbing structure adapted to be inserted into a through-hole formed in a wall portion of a fuel tank, includes a first pipe adapted to be attached to the fuel tank; a second pipe coaxially connected to the first pipe; a flexible locking piece protruding in one of either the first or second pipe; a locking portion formed in the other of the first or second pipe, and locking the locking piece; and a lock member to be displaceable between a predetermined first and second position. While the lock member is separated from the locking piece in the first position to allow an engagement and a disengagement of the locking piece and the locking portion, the lock member abuts against the locking piece in the second position to prevent the disengagement of the locking piece from the locking portion.

A jet pump has a jet nozzle that discharges an operating fluid, a chamber into which a transfer fluid flows and which encloses the end of the jet nozzle, a throat pipe having a constriction portion and a jet nozzle through which the transfer fluid that flows into the chamber is discharged. The discharge end of the throat pipe has a smaller diameter than the base end, and is bent at an angle of approximately 90 degrees from the base end.

A fuel filter of the invention is attached to a suction side of a fuel pump. The filter includes a bag member made of a filtration material, a cylindrical portion provided to the bag member to allow the suction side of the fuel pump to communicate with an interior of the bag member, and a shape keeping frame for the bag member extending from the cylindrical portion to an inside of the bag member. The shape keeping frame includes a plate shape portion to make a surface contact with an inner surface of the bag member in front of an opening of the cylindrical portion inside the bag member. Thus, the fuel filter does not impair a suction ability of the fuel pump even if a space between the opening of the cylindrical portion as the suction side of the fuel pump and the inner surface of the bag member opposed thereto is narrow.
