Abstract
A fuel supplying device for an internal combustion engine includes a tank configured to store a gaseous fuel, a fuel injection valve configured to supply the gaseous fuel to a cylinder of the internal combustion engine, a fuel passage configured to supply the gaseous fuel in the tank to the fuel injection valve, and a pressure reduction valve provided in the fuel passage. The fuel passage has a double-walled pipe structure including an inner pipe through which the gaseous fuel flows and an outer pipe that has an inner diameter larger than the inner pipe and covers the inner pipe. The fuel passage is configured such that a coolant is supplied to a space between the outer pipe and the inner pipe.
