An electric actuator comprises an actuator body which is a rectangular tube have having two pairs of opposing surfaces disposed in parallel and which has a slit formed to extend by a predetermined length along an edge of the rectangular tube; a slider which reciprocates along the slit of the actuator body by a rotary driving source; the rotary driving source which is connected to one end of the actuator body; and a driving force-transmitting mechanism which converts the rotary driving force of the rotary driving source into the rectilinear motion which is transmitted to the slider.

1. Field of the Invention
The present invention relates to an electric actuator which makes it possible to allow a slider to reciprocate linearly along an actuator body, and a method of assembling the same.
2. Description of the Related Art
FIG. 1 is a perspective view illustrating an electric actuator according to an embodiment of the present invention;
FIG. 2 is an exploded perspective view illustrating the electric actuator shown in FIG. 1;
FIG. 3 is a perspective view illustrating a rotary driving source and a driving force-transmitting mechanism of the electric actuator shown in FIG. 1;
With reference to FIGS. 1 and 2, reference numeral 10 indicates an electric actuator according to an embodiment of the present invention.
The electric actuator 10 comprises an actuator body 16 which is a rectangular tube having two pairs of opposing surfaces disposed substantially in parallel to one another and which has a slit 14 formed to extend linearly by a predetermined length along an edge 12 of the rectangular tube, and a rotary driving source (driving source) 18 which is connected to one end of the actuator body 16.
In this arrangement, the actuator body 16 is the flat rectangular tube in which the dimension in the horizontal direction is larger than the dimension in the height direction in order to respond to an environment of installation in which the dimension in the height direction is restricted.
