The present invention relates to a servo with a rudder tray function. The servo comprises a lower case (110), an upper case (120), a motor (111) provided inside, a reduction gear unit (112) configured to reduce a driving output of the motor (111), and an output shaft (130) connected to a final reduction gear (113) of the reduction gear unit (112) and protruding outside the upper case (120). More specifically, the servo (100) with a rudder tray function comprises: a servo arm support bearing installation part (121) formed around the output shaft (130) on the upper surface of the upper case (120); a servo horn (140) coupled to the output shaft (130); a servo arm (150) coupled to the servo horn (140) and having a bearing installation protrusion (151) at the lower center; and a servo arm support bearing (160) installed between the servo arm support bearing installation part (121) and the bearing installation protrusion (151). According to the present invention, the upper case of the servo can drive the servo arm receiving a large load by only the servo itself while supporting the servo arm through the bearing, without using a separate rudder tray servo mount, thereby greatly simplifying the configuration and installation and significantly improving mechanical characteristics and reliability. |
