PURPOSE:To improve the durability while to reduce the cost of driven board by arranging clutch facings mainly composed of string material hooked by many times at the opposite sides of center plate then binding through resin component and molding integrally. CONSTITUTION:The outer shapes of clutch facing 201, 202 molded integrally with string material hooked by many times and resin component filled in the gap sections are made larger than a center plate 15. Since the facings 201, 202 will contact directly, firm binding cam be achieved. While since a communication hole 15b is made through the center plate 15, firmer binding can be achieved between the facings 201, 202. A driven board 3 pressure molded in such a manner has excellent withstandability.
