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 assembly does not take time and effort, and further, in which a biasing force of an biasing member can be adjusted from the outside after the assembly. An inner side spring presser (15) includes a shaft portion (22) and a cylinder portion (23) provided at a lower edge portion of the shaft portion (22), and presses an upper side peripheral edge portion of a through hole (12a) of a biasing member (12) by a lower end of the cylinder portion (23). The shaft portion (22) penetrates an outer side spring presser (16) and extends upwardly. An adjustment screw (19) which positions the inner side spring presser (15) as a lower end abuts against an upper surface of the shaft portion (22) of the inner side spring presser (15), is screwed to a top wall (11d) of a casing (11). |
