Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a data radio transmission system for normally performing communication between slave machines and master machines even for the slave machines in which an obstacle that interrupts radio waves exists between it and the master machine, without requiring arrangement intervals between the respective slave machines and the master machines to be necessarily set within the maximum reaching distance of the radio waves and for extending the arrangement intervals. SOLUTION: The data radio transmission system is provided with a plurality of slave machine 1 to 4 and the master machine 5 that controls each of a plurality of the slave machines 1 to 4 and transmits data between each of the slave machines 1 to 4 and the master machine 5 by using radio communication. Each of a plurality of the slave machine 1 to 4 is provided with relay means 20, 21, 23 for relaying the data in the case of transmitting the data between other slave machines and the master machine 5.
