PURPOSE:To enable woodwork products having rounded angle parts to be polished efficiently by the operation of the roller installed on a pantagraph mechanism and the sander belt stretched between tension rollers. CONSTITUTION:One edge part of each arm 3 of a pantagraph mechanism is pivotally installed 4, and one edge of a crank arm 5 of an angle shape is pivotally installed 6 onto the other edge part, and each roller 8 is installed onto the other edge of the crank arm 5 of each angle shape. Onto the pivot 4, the split groove 11 form on one edge of the operating member 10. The other edge of which is fixed on the member driven by a driving device 12 is fitted. A sander belt 15 is stretched along the roller 8, a driving roller 14, and a tension roller 13, and a pinch roller is installed onto the roller 14, to drive the sander belt 15.
