The surface of the carbon fiber reinforced plastic 41 is plated with nickel and/or chromium to enhance the mechanical strength of the carbon fiber strength plastic. At this time, since the surface of the carbon fiber reinforced plastic to which the plating is applied is bonded to the stainless steel 43 by the conductive adhesive, the electrostatic discharge circuit can be surely secured. Further, the electric material is made of nickel and/or chromium. However, the present invention is not limited to these, and it is also possible to appropriately determine the function, workability, cost, and the like. (Effect of the Invention) The following is a comparison value between the weight of the rubbing roller used in the conventionally used rubbing cloth and the weight and the amount of deflection of the carbon fiber reinforced plastic rubbing drum of the present invention. Compare the sample size to the shape of mm, thickness 7.5mm, length 24 ;; material is the specific gravity / two, weight 21.5kg carbon fiber reinforced plastic and the use of specific gravity 27, weight Μ Ming ' and constitute the third figure The friction roller of the invention and the conventional friction roller of the heart shown in Fig. 5. As a result, the friction roller using the carbon fiber reinforced plastic of the present invention in terms of weight was reduced by about 40% compared with the conventional one (4), and in terms of the maximum deflection amount, the end portion was the support portion of the support portion. On the top, the friction roller using carbon fiber reinforced plastic is o.cm, and the use is 〇〇78_, which shows that the friction roller using carbon fiber reinforced plastic is about 1/3 to 1/4 lighter than aluminum. Quantify. 1 Therefore, the use of carbon fiber with a known aluminum is more lightweight and the reinforced plastic friction roller is used to improve the replacement of the friction roller itself, and the loading and unloading of the 314754 9 1293710 friction cloth, and the movement of installation and handling. Workability. In addition, as the size of the liquid crystal display element increases, the friction roller also needs to be enlarged, but the amount of deflection of the day is also smaller than that of the conventional aluminum, and the frictional pressure of the alignment film is not high. Uniformity maintains a good display level for the enlargement of the liquid crystal display element. Moreover, the dust-proof pair is applied: the static electricity generated during the sacrifice can be discharged without accumulating in the friction roller, so that the alignment film on the alignment film of the liquid crystal display substrate can reduce the adsorption film on the alignment film. The floating dust or the % hair which is detached from the rubbing cloth, etc., reduces the defects caused by the display failure of the liquid crystal display element, and can be produced to the yield of the production.
