PURPOSE: Structure for combining a rod of a servo motor with a coupling is provided to improve productivity by making assembling and disassembling easy and to promote the quality of a product and the reliability of consumer by removing a backlash. CONSTITUTION: A servo motor(100) is inserted to the outer face of a rod(600) transmitting the rotational force. A coupling(200) inserted to the outer face of the rod connects two shafts and transmits power. A helical gear(300) inserted to the coupling is operated smoothly with low noise. The helical gear transmits a strong force. A coupling combining unit is combined with the rod of the servo motor. Herein, a washer is closely adhered to the upper portion of the helical gear. A hexagonal bolt is inserted to be combined with the threaded portion of the rod. By rotating the hexagonal bolt, the coupling and the helical gear is assembled and disassembled easily.
