A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap form the outer end of the tank filler pipe.

An automatic opening and closing device for a fuel inlet of a vehicle may include a cap cover mounted at the fuel inlet of the vehicle, a fuel cap pivotably mounted at the cap cover and configured to selectively open or close the fuel inlet by being pivoted inside the fuel inlet, and a fuel cap operating mechanism mounted in the fuel inlet and configured, when the fuel door is closed, to pivot the fuel cap by being pressed by the fuel door to close the fuel inlet, and, when the fuel door is opened, pivot the fuel cap to open the fuel inlet according to release of pressing by the fuel door.

A tank made of resin provided with a barrier layer, which prevents the barrier layer from rolling up and has improved d urability. In a tank made of resin that includes a barrier layer provided on an inner surface of a tank body made of resin, an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which the casting flange part is located at the thick part.

An fuel inlet port structure includes an inlet box having a box shape and having a box opening at its bottom, an inner panel disposed further inward of a vehicle with respect to the inlet box, and an inlet shield inserted through the box opening of the inlet box from outward of the vehicle and disposed between the inlet box and the inner panel. The inlet shield includes a barrel portion having a groove extending circumferentially along part of an entire circumference of an outer surface of the barrel portion at an outer edge.

A fuel filling and vapor recovery system for a vehicle is described. The system includes: a canister that is in communication with a fuel receptacle in the vehicle to collect and filter fuel vapor; a first tube that is connected to the canister; a second tube that is connected to the fuel receptacle; and a canister box that is configured for connection to the first and second tubes. The canister box includes an upper member, and a lower member that is configured for engagement with the upper member such that a watertight seal is formed therebetween to prevent external water intrusion into the canister box. The lower member includes an integral connector that is configured for connection to the first tube to allow the fuel vapor to enter the canister box.

A tank filler tube includes a fill tube line which features, in the tank assembled state, an inlet end further from the tank, which is designed for temporary insertion of the fill nozzle into a closer-to-the-tank insertion region of the fill tube line, and with a closer-to-the-tank transit line end in the tank assembled state, which is designed for transit of liquid in a direction of the liquid transit line leading away from the inlet end, wherein the fill tube line is of multi-part design. At least one part of the ventilation line is for venting the gas displaced during a filling of a tank into the atmosphere. The fill tube line section featuring the transit line end extends into the insertion region further from the tank and is designed to accommodate at least one outlet end of a fill nozzle during a filling of a tank.

A vehicle equipped with a high pressure tank has mounted in the interior of a vehicle body a high pressure tank having a resin liner and a reinforced layer, the vehicle comprising a tank chamber, a filling port, a concave portion in which the filling port and a ventilation port are disposed, a fuel lid capable of opening and closing an opening of the concave portion, and a ventilation passage that allows communication between the ventilation port and the tank chamber. When the fuel lid is opened, the ventilation port is opened to the exterior of the vehicle body, whereas when the fuel lid is closed, the ventilation port is covered by the fuel lid in a state in which the ventilation port is allowed to communicate with the exterior of the vehicle body.

A drainage portion extending from one to the other of a bottom wall of a recess and a lid is provided at least above a hydrogen filling port in the recess when the lid is in a closed state. Therefore, water, which has entered the recess from a gap (parting) when the lid is in a closed state, reaches an upper surface of the drainage portion and flows along the upper surface of the drainage portion, and then, the water flows down from the drainage portion while avoiding the hydrogen filling port. Accordingly, it is possible to suppress the water having entered the recess while the lid is in a closed state from adhering to the hydrogen filling port.

A refueling retainer comprises a body portion of a tubular shape inserted into and arranged at a fueling-side end portion of an inlet pipe through which fuel is introduced to a fuel tank. The body portion comprises at a leading end portion thereof: a tapered portion, which is an inner peripheral surface of the leading end portion inclined radially inward toward a leading end of the body portion; and a claw portion that projects from the leading end of the body portion in an inwardly bent manner.
