To provide a fuel inlet improved in collision resistance.

A cylindrical retainer 10 is inserted into an inner periphery on the tip side of an inlet pipe 2. A cavity 18 reaching the insertion side end of the retainer 10 is formed by being recessed to the radial direction inside on the insertion side of the retainer 10. The tip of a breather tube 4 is fixed in the cavity 18, and the inlet pipe 2 and the breather tube 4 are bent and formed together with the breather tube 4 inserted into the inlet pipe 2. A cut-out 20 is formed at the breather tube 4 in the cavity 18 and the breather tube 4 is inserted into the inlet pipe 2. The inlet pipe 2 is connected to a fuel tank T, the breather tube 4 is inserted into the fuel tank T by passing through the inlet pipe 2, the breather tube 4 is bent to an upper side in the fuel tank T, and a discharge hole 30 is formed at a lower position of the breather tube 4.
