Abstract
A gaseous fuel filling structure includes a coupler connected to a gaseous fuel supply system, a gaseous fuel cylinder that stores a gaseous fuel at a high pressure, a fuel dissipation preventing device that prevents dissipation of the gaseous fuel, and a switching device that is selectively placed in a first state in which the coupler is connected to the gaseous fuel cylinder and disconnected from the fuel dissipation preventing device, or a second state in which the coupler is connected to the fuel dissipation preventing device. The switching device includes a member(s) for preventing back flow of the gaseous fuel from the gaseous fuel cylinder toward the coupler.
