PURPOSE:To heighten the durability of the rubber of an elastic workpiece receiving part very much, by embedding thick reinforcing wires in the rubber in one direction and thin reinforcing wires therein in another crossing direction. CONSTITUTION:Thick wires or fibers 12 are embedded in the rubber 11 of an elastic workpiece receiving part 10 in one direction such as the lateral direction. Thin wires or fibers 13 are embedded in the rubber 11 in another crossing direction such as the longitudinal direction. As a result, the longitudinal deflection of the surface of the rubber 11 is facilitated so that its fitness to a workpiece is greatly enhanced. Since the load of the workpiece on the rubber 11 is efficiently distributed therein by the thick wires or fibers 12, the durability of the rubber is heightened very much. |
