PROBLEM TO BE SOLVED: To provide a pressure reducing device which can be used for both high pressure operating equipment and low pressure operating equipment, and to make a compressed gas supplying device compact and lightweight by using the pressure reducing device. SOLUTION: A pressure reducing device 2 inputs compressed gas in a first pressure level from an inlet 21, and outputs compressed gas obtained by reducing the compressed gas to a high pressure level which is not more than the first pressure level from a first outlet 10 and a second outlet 11. A single pressure reducing valve 22 is used so that the compressed gas in not more than a second high pressure level which is lower than the first pressure level being the maximum pressure level in which the pressure reducing valve can operate can be outputted from the first outlet 10. Also, a pressure-sensitive closing valve 26 is used so that only the compressed gas in not more than a third pressure level which is lower than the second pressure level can be outputted from the second outlet 11. |
