PROBLEM TO BE SOLVED: To provide a filler opening capable of not only preventing blowing-back fuel from being sprayed on a fuel filling worker while filling fuel, but also preventing the blown-back fuel from blowing off from an opening end of the filler opening.SOLUTION: A first insertion part 1 and a second insertion part 2 which are across each other in the insertion direction of an oil supply nozzle 5 are arranged in this order from an opening end 311. The first insertion part 1 has an insertion opening 11 in which the diameter of an inner circumferential edge is equal to the outside diameter of the oil supply nozzle 5. The second insertion part 2 has guide bars 21 copying the outside diameter of the oil supply nozzle 5 in an interrupting manner in the circumferential direction. In the filler opening, a flow-out port 23 for communicating a guide space 22 surrounded by the guide bars 21 with the outer side of the oil supply pipe 5 is provided between the guide bars 21 adjacent to each other in the circumferential direction. |
