PROBLEM TO BE SOLVED: To provide a coupling structure of a fuel tank with a filler pipe capable of simply and reliably coupling an inlet lower pipe with a filler pipe. SOLUTION: A lock ring 26 is rotatably mounted on a base end side of an inlet lower pipe 14 protruded from a fuel tank 10. The lock ring 26 has a first engagement part 42 and a second engagement part 44. The second engagement part 44 is located in a space of a mounting plate 16, and an end on the coupling side of a filler pipe 20 is inserted in the inlet lower pipe 14 in this state. After the first engagement part 42 is advanced into a first groove part 46A of a part 46 to be engaged, the lock ring 26 is turned to advance the first engagement part 42 into a second groove part 46B, and the filler pipe 20 is coupled with the inlet lower pipe 14. Thus, the fuel tank and the filler pipe can be simply and reliably coupled with each other. COPYRIGHT: (C)2005,JPO&NCIPI
