動板を形成していた。(Prior art) Conventionally, automobile clutch driven plates have been made using long fibers such as asbestos or glass fiber as a fiber base material, and thermosetting resin, rubber material, and other 1° to 3° friction modifiers are applied to the fiber base material. The woven clutch driven plate was formed by impregnating it, rolling it into an annular shape, preforming it, then hot-pressing it, and finishing it by after-curing, deburring, and polishing.

As disclosed in Publication No. 70225, a resin-molded clutch facing plate made of asbestos nonwoven fabric, thermosetting resin, friction, and g alignment is placed on a bank-up material made of a light alloy such as aluminum, duralumin, and magnesium. Clutch driven plates integrally formed by thermo-pressure molding are also known. Compared to the manufacturing method of woven clutch driven plates, this clutch wave tentative manufacturing method does not require the process of impregnating the fiber base material with a binder or friction modifier, or the process of preforming by rolling it into a tablet, reducing time and processing costs. You can save money. Furthermore, this clutch driven plate is generally more stable in quality than a woven clutch driven plate, and has a high breaking rotational speed because it is reinforced with a backup material.

ッチ被動板が反ってしまう。(Problem to be Solved by the Invention) However, the clutch driven plate manufactured by the above-mentioned manufacturing method has problems due to the difference in coefficient of thermal expansion between the backup material and the clutch facing member, and the curing shrinkage of the binder of the clutch facing member. The clutch driven plate warps during the process of integrally thermoforming.

ことからクラッチ被動板のバースト強度が高くなる。(Function) In the present invention, a plurality of dimples are formed on the surface of the clutch facing member by the above means.
The stress generated due to the difference in thermal expansion coefficient between the backup material and the clutch facing member is reduced at the dimple portion, and warpage is reduced accordingly. In addition, since the amount of the clutch member to be loaded is reduced by the volume of the dimple, the weight of the clutch driven plate can be reduced, and the weight of the clutch driven plate can be reduced. Since the moment of inertia of the clutch facing member is reduced, the burst strength of the clutch driven plate is increased.
更に、バックアップ材に吸気孔を設けているので、高速
聞伝でクラッチを断接する際、ディンプルで負圧が発生
