していた。(Prior art) Conventionally, the manufacturing method of automobile clutch driven plates uses long fibers such as asbestos and glass fibers as a fiber base material, and adds thermosetting resin, rubber material, other friction modifiers, etc. to the fiber base material. The woven clutch driven plate was formed by impregnating it with the following materials, preforming it by winding it into an annular shape, and then heat-pressing it, and finishing it by after-curing, deburring, polishing, etc.

る。On the other hand, JP-A-61-41022 and JP-A-61-41022,
As disclosed in Japanese Patent No. 70225, a resin-molded clutch facing plate made of asbestos nonwoven fabric, a thermosetting resin, and a friction modifier is mounted on a back-up material made of a light alloy such as aluminum, duralumin, or magnesium. There is also known a method of manufacturing a clutch driven plate which is integrally formed by thermo-pressure molding. Compared to the manufacturing method of woven clutch driven plates, this clutch driven plate manufacturing method saves time and processing costs because it does not require the process of impregnating the fiber base material with a binder or friction modifier, or the process of wrapping it into a tablet and preforming it. can.
更に、このクラッチ被動板は、ウーブンクラッチ被動板
に比較して一般に品質か安定しており、バックアップ材
によって強度が補強されているので破壊回転数が高い。Furthermore, this clutch driven plate generally has more stable quality than a woven clutch driven plate, and has a high breaking rotational speed because its strength is reinforced by the backup material.

った。(Problems to be Solved by the Invention) However, the clutch driven plate manufactured by the above manufacturing method has a heavier gravity than the woven clutch driven plate.
In order to use this for clutch discs, it was necessary to increase the strength of the transmission synchronizer.

。In order to improve this, a method was considered in which a mold with a cylindrical protrusion was used as shown in Fig. 6, and a plurality of dimples were formed at the same time as the hot press molding, thereby making the clutch driven plate lighter.

ェーシング部材も密度の低いもろい部材となるという不
都合があった。However, if you try to form dimples at the same time as hot-press molding, since the clutch facing member has poor flowability, the clutch facing member will remain in the dimple area between the cylindrical protrusion and the backup material, and the clutch driven plate will not be fully formed. Not only is the lightweight effect not achieved, but the clutch facing member also has the disadvantage of being a brittle member with low density.

。Specifically, the backup material of the present invention is a ring-shaped plate made of metal such as steel, copper, aluminum, duralumin, and magnesium, and is made of metal such as aluminum, duralumin, and magnesium with a specific gravity of 5 or less. It is preferable to use a light metal because the total specific gravity is low. In addition, the surface that becomes the joint surface with the backup clutch facing member is roughened by shot blasting, puff polishing, chemical processing, etc. because adhesives such as epoxy, phenol, and nitrile phenol are applied. It is a face.
