A small-sized linear servo actuator is disclosed. The small-sized linear servo actuator, according to one embodiment of the present invention, comprises: a rod part having the overall shape of a rod and receiving driving force so as to carry out linear reciprocating motion; a servo motor having a rotating shaft for supplying driving force for driving the rod part; a power transmission member for converting rotational motion by the rotating shaft of the servo motor into the linear reciprocating motion of the rod part; an outer housing having a guide hole formed at one side thereof and penetrated by one end of the rod part, a hollow part formed therein along the central axis direction of the guide hole so as to accommodate the rod part, an accommodation space formed at the upper side of the hollow part so as to accommodate a potentiometer for measuring the movement distance of the rod part and a control board for controlling all of the operations, and an accommodation space formed at the lower side of the hollow part so as to accommodate the servo motor; and a pivot joint part provided with a joint main body, which has a plurality of cylindrical members having the same central axis but different diameters from each other and double-overlapped with each other, and a joint shaft, which vertically penetrates a side surface of the joint main body and is rotationally coupled to one end of the outer housing such that reciprocating rotational motion can be implemented for two shafts which are relatively perpendicular to each other, thereby obtaining two-degrees-of-freedom. |
