PROBLEM TO BE SOLVED: To provide an air supply and discharge device capable of being easily manufactured and being fit for specification change by effectively utilizing a device space while reducing vibrations generated from a pump even in a solenoid valve. SOLUTION: This air supply and discharge device is constituted such that two or more solenoid valves provided with a supply port 31, a distribution port 32 and a discharge port 33 are prepared and a plurality of solenoid units 80 for which the plurality of solenoid valves 30 are integrated are provided. Thus, compared to the integration type of all the solenoid valves 30, even when the vibrations by the pump 20 reach the solenoid valve units 80 through a supply path, they are dispersed to the plurality of solenoid valve units 80 and the vibrations are prevented. Also, while the integrated type of all the solenoid valves 30 becomes long locally in a fixed direction and enlarged, the plurality of the solenoid valve units 80 are miniaturized without becoming long locally in the fixed direction by arranging one solenoid valve unit 80 on one surface and arranging the other solenoid valve unit 80 on the other surface. Further, compared to the arrangement of each solenoid valve 30, the constitution of the plurality of solenoid valves 30 is easily assembled and the specification change can be coped with even when it occurs compared to the integrated type of all the solenoid valves 30.
