Abstract

[Problem] To provide a technique capable of detecting a state of gas fuel that flows in an inner pipe and preventing leakage of the gas fuel to the outside of an outer pipe. [Solution] A gas fuel flow device is a gas fuel flow device of an engine that combusts a gas fuel comprising: a double pipe including an inner pipe through which the gas fuel flows, and an outer pipe that is placed with a predetermined gap between the outer pipe and an outer peripheral surface of the inner pipe. The double pipe is provided with a detection portion that detects a state of the gas fuel. The detection portion includes a state detection sensor that is arranged to extend from an inside of the inner pipe to an outside of the outer pipe, and a cover portion that covers a protruding portion of the state detection sensor that protrudes from the outer pipe.
