PROBLEM TO BE SOLVED: To solve a problem that in inter-device connection constituted by a fuel supply part, a fuel receiving part, and a fuel transfer pipe for connecting them, a wire for sending and receiving an electric signal is arranged in order to transfer information between the fuel supply part and the fuel receiving part, an information transfer device in a simple structure exhibiting high safety is desired. SOLUTION: The information transfer by sound wave can be performed with the usage of pressure change of a gas or a liquid transferred in a fuel supply pipe in this information transfer device. The fuel delivery and the information transfer can be performed by a same path without providing another signal wire other than the fuel supply pipe. Thus, the information transfer device exhibiting high safety in a simple structure can be provided. |
