Abstract
There is provided a fluid controller actuator which does not require a plurality of bolts for fixing an inner side spring presser to a casing, in which a configuration is simple and a biasing force of an biasing member can be adjusted from the outside after the assembly. An inner side spring presser includes a shaft portion and a cylinder portion provided at a lower edge portion of the shaft portion, and presses an upper side peripheral edge portion of a through hole of a biasing member by a lower end of the cylinder portion. The shaft portion penetrates an outer side spring presser and extends upwardly. An adjustment screw which positions the inner side spring presser as a lower end abuts against an upper surface of the shaft portion of the inner side spring presser, is screwed to a top wall of a casing.
