Abstract: 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.

Abstract: A valve device is used by being attached to a fuel tank. The valve device includes a main body portion provided with ventilation openings which become an inner end of a connecting passage with the outside of the fuel tank, a valve body opening and closing the ventilation openings using a liquid surface of a fuel, and a skirt portion extending down from the main body portion so as to surround the valve body, and also constructed so as to admit fuel due to a pressure difference between inside and outside of the fuel tank when the liquid surface of the fuel reaches a cuff portion of the skirt portion.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A cup holder unit includes an outer case, an inner case slidable between a pulled-out position and a stored position, a main holder member slidable between a usable position and a non-usable position, and a connecting member pivotally supported on the inner case. The connecting member has an abutment section to abut against a corresponding section of the main holder member halfway through pulling of the main holder member from the non-usable position so that the main holder member can be pulled out together with the inner case, and a tab to engage a notched section when the inner case is substantially fully pulled out to the pulled-out position. A disengaging abutment section is formed at the connecting member to disengage the tab from the notched section by abutting against the corresponding section halfway through pushing the main holder member from the usable position to the non-usable position.

Abstract: 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.

Abstract: 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.
