Abstract

A fuel inlet 10 includes a fuel inlet body 11 that is formed of resin including a reception pipe portion 20 , a filler pipe connection pipe portion 30 , a breather pipe connection pipe portion 40 , and a fluid introduction portion 60 . The reception pipe portion 60 receives a fuel nozzle 3 . The filler pipe connection pipe portion 30 is located on a lower side of the reception pipe portion 20 and is connected to a filler pipe 31 . The breather pipe connection pipe portion 40 is located on an upper side of the reception pipe portion 20 and is connected to a breather pipe 41 . The fluid introduction portion 20 causes foamed fluid to flow along an inner wall surface of the reception pipe portion 20 while liquefying the foamed fluid, the foamed fluid flowing from the breather pipe connection pipe portion 40 to the reception pipe portion 20 . The fuel inlet body 11 that is formed of resin is formed by integrally molding the reception pipe portion 20 , the filler pipe connection pipe portion 30 , the breather pipe connection pipe portion 40 , and the fluid introduction portion 60 .

First claim

The invention claimed is:

1. A fuel inlet, comprising:
a fuel inlet body that is formed of resin, the fuel inlet body including
a reception pipe portion that has a first end portion and a second end portion, and receives a fuel nozzle at the first end portion,
a filler pipe connection pipe portion that is located on a lower side of the second end portion of the reception pipe portion and is connected to a filler pipe,
a breather pipe connection pipe portion that is located on an upper side of the second end portion of the reception pipe portion and is connected to a breather pipe, and
a fluid introduction portion that has an introduction plate, the introduction plate being formed to have a plate-like shape, formed to project toward the first end portion from an inner wall surface of the second end portion between the filler pipe connection pipe portion and the breather pipe connection pipe portion, having a top surface portion that extends inclined at a predetermined angle and having a notch, the fluid introduction portion causing foamed fluid to flow along an inner wall surface of the reception pipe portion while liquefying the foamed fluid with the introduction plate, and the foamed fluid flowing from the breather pipe connection pipe portion to the reception pipe portion; and
a nozzle insertion portion connected to an end portion of the reception pipe portion, wherein
the nozzle insertion portion includes a lid configured to be capable of pivoting between a first position and a second position, the lid blocking internal space of the reception pipe portion from external air at the first position, the lid opening the internal space of the reception pipe portion to the external air at the second position, and
the lid is located in the notch at the second position, and an outer surface of the introduction plate and the top surface portion of the lid are connected to each other.

2. The fuel inlet according to claim 1 , wherein
the fuel inlet body that is formed of resin includes a pair of placement walls, each of the placement walls being formed to have a plate-like shape, each of the placement walls being erected on the inner wall surface on a lower side of the reception pipe portion, each placement wall extending to the filler pipe connection pipe portion, the placement wall introducing the fluid that has been caused to flow along the inner wall surface of the reception pipe portion into the filler pipe connection pipe portion, the fuel nozzle being placed on the pair of placement walls on a tip side of the fuel nozzle.
