<p><P>PROBLEM TO BE SOLVED: To largely increase heat resistance by sufficiently increasing heat capacity without adding a new step and reducing the wear resistance of a lining in a multi-disk frictional engagement device. <P>SOLUTION: Three sheets of external gear wet friction members forming the multi-disk frictional engagement device 1 are formed by adhering the lining 5 onto the entire peripheral one surface of an external gear plate 2. Three sheets of internal gear wet friction members are formed by adhering the lining 5 onto the entire peripheral one surface of an internal gear plate 3. Since the internal gear plate 3 is advantageous to the external gear plate 2 with respect to heat-dissipating property, the heat capacity of the external gear plate 2 can be increased without increasing a pack amount by decreasing the thickness of the internal gear plate 3 and increasing, by just that much, the thickness of the external gear plate 2. Consequently, the entire heat-dissipating property of the multi-disk frictional engagement device 1 can be largely increased. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
