Abstract
Official abstract text for this publication.
An object is to suppress excessive insertion of a fueling nozzle during fueling. A nozzle guide configured to form a nozzle guide path that guides a fueling nozzle is placed inside of a filler neck main body configured to include a fuel passage that introduces a fuel supplied from the fueling nozzle toward a fuel tank. This nozzle guide comprises a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel supply apparatus, comprising: a filler neck main body including an opening configured to receive a fueling nozzle inserted therein, and a fuel passage configured to introduce a fuel supplied from the fueling nozzle toward a fuel tank; and a nozzle guide placed inside of the filler neck main body on an opening side and configured to form a nozzle guide path that guides the fueling nozzle, wherein the nozzle guide includes: a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path, the first projection and the second projection are projections protruded from the end opening circumferential wall at different positions about an axis of the nozzle guide path, the first projection is one of two first projections protruded on the nozzle guide end opening portion to be opposed to each other, and the second projection is a projection protruded from the end opening circumferential wall in a center region between the two first projections opposed to each other.
