In a robot servo mechanism, the servo mechanism is installed within a L-shaped housing box to make dimension thereof smaller with smaller dead space thereof. In the servo mechanism, each of first and second housing boxandof a robot servo unit has a small motor, a reduction unit and a potentiometer. Since, each of the two housing boxesandhas L-shaped configuration, each of corresponding connection spacesandsurrounded by one dotted chain line can be formed. First and second output shaftsandare installed with protrusion into the connection spacesand, respectively. A cross-shaped coupling bodyhaving a cross-type through hole formed therein is fitted around the output shaftalong a line indicated by an arrow and then fixed thereat by using a screw. Then, the second output shaftof the second housing boxis inserted into the cross-shaped coupling body previously fixed at the first housing box. As a result, the two housing boxesandare integrated as one body through the use of the cross-shaped coupling body, thereby constructing a joint servo of a robot.
