An object is to enhance the assembly of a breather pipe which is accommodated in a filler pipe. A nozzle guide () that is arranged within a filler pipe () includes: a main body portion () that guides the insertion and removal of a refueling nozzle (); and a connection member (to) that is provided on an outer circumferential surface () of the main body portion () and in which an upper end portion () of the connection member is located, in a tank direction (TD) extending from a refueling port (FC) toward a fuel tank (FT), on a downstream side with respect to a tip end portion () of the refueling nozzle (), and the connection member (to) includes: a connection portion () connected to a breather pipe () that is arranged within the filler pipe (); and a vapor flow path formation portion () that forms part of a vapor flow path () for the fuel vapor that flows in through the breather pipe () and the connection portion ().

Nozzle guide

In a housing surrounding a nozzle insertion passage, a first opening open to the atmosphere is provided, and in a cover main body in which the housing is incorporated, a nozzle insertion port and a second opening which is opposite the first opening and open to the atmosphere is provided. Moreover, in the recess wall of a drainage port formation member fitted to the first opening, a recess which is recessed on the side of the first opening is formed so as to be continuous with the second opening, and a drainage port is provided. A drainage valve is held in the recess with respect to the recess wall so as to open and close the drainage port by turning of the valve main body about the turning shaft serving as a base point.

Opening/closing device of fuel tank

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.
