In the actuator, a short bent base portion is provided at the end portion of the first turn of the return spring, and the end portion of the first turn of the return spring rides on the bent base. An actuator characterized in that the first turn of the return spring is fixed to the casing by its elastic force, and the return spring is disposed between the diaphragm side and the casing side.
