。 The inner chamber of the case is separated into a diaphragm chamber and a second chamber by a combo-type diaphragm extended within the case and having a curved portion, and the diaphragm is separated into a second chamber by applying operating pressure to the diaphragm chamber. In the diaphragm actuator, the case is provided with a valve hole that communicates the diaphragm chamber with the atmosphere, and the diaphragm chamber is connected to the valve hole. 1. A diaphragm actuator, characterized in that a diaphragm actuator is provided with a valve element that can be freely approached and separated, and which performs an opening operation when the pressure becomes opposite to the operating pressure.
