Fuel device

A fuel device configured to accept a fuel nozzle, the fuel device comprising:

• a fuel supply port forming portion including a fuel supply port configured to accept a fuel nozzle and forming a portion of a fuel passage from the fuel supply port to a fuel tank;
• a discriminating portion provided in a region in which the fuel nozzle inserted from the fuel supply port reaches, the discriminating portion configuring a discrimination opening formed of a first portion and a second portion, the first portion being an opening corresponding to an external diameter of a small-diameter nozzle having an external diameter smaller than a fuel nozzle compatible with the fuel device, and the second portion being an opening having a shape corresponding to an external diameter of a large-diameter nozzle compatible with the fuel device;
• an operation member provided in the discriminating portion and configured to guide the small-diameter nozzle intended to insert into the second portion to be inserted into the first portion;
• an abutting member provided closer to the fuel tank than the discrimination opening of the discriminating portion, the abutting member preventing a tip of the small-diameter nozzle from passing the first portion;
• and
• an open/close member provided closer to the fuel tank than the discriminating portion, the open/close member being biased from the fuel tank toward a close direction and caused to enter an open state by the large-diameter nozzle passing through the second portion of the discrimination opening,
• wherein the operation member further includes a start-up member upon which a tip of the fuel nozzle inserted from the fuel supply port abuts,
• the start-up member is disposed at a position at which the second portion includes an inner dimension portion smaller than the external diameter of the large-diameter nozzle, and
• the abutting member is moved toward the start-up member when the tip of the small-diameter nozzle abuts against the start-up member and the start-up member moves when the large-diameter nozzle abuts against the start-up member, to thereby expand the inner dimension portion of the second portion further than the external diameter of the large-diameter nozzle.

• a guide member formed at a predetermined height close to the fuel supply port at a position at which the first portion and the second portion of the discriminating portion are connected;
• and
• the operation member configured to prevent passage of the small-diameter nozzle through the discrimination opening by guiding the small-diameter nozzle to the first portion, the small-diameter nozzle being inserted into the discrimination opening,
• wherein the guide member includes a first guide inclined face inclined toward the first portion closer to the fuel supply port.

• wherein a side of the guide member close to the fuel supply port includes a second guide inclined face inclined toward the second portion while reducing in diameter, and
• a side of the guide member opposite to the fuel supply port is formed into a shape forming a space in a predetermined region from an inner peripheral edge of the discrimination opening outward.
