PURPOSE: To stabilize the load worked on a motor by energizing a turning plate with a spring and pressing an intermediate pulley against a toothed belt when a discrepancy is generated between a layout length of the pulley and a circumferential length of the toothed belt.
CONSTITUTION: The turning plate 6 is turned around a fulcrum as the center shaft 7. A clockwise moment is imparted to the turning plate 6 by energizing it with a spring 8. Then, the intermediate pulley 5 is press-fitted into a bearing to be restrained and the toothed belt 4 is pressed on its side having a rotary shaft as the center by the intermediate pulley 5, so that the toothed belt 4 is kept constant in tension. By such constitution, when a discrepancy between the layout length of the pulley and the circumferential length of the toothed belt 4 is generated, the tension of the toothed belt becomes constant, and the load to b worked on the motor can be stabilized.
