PURPOSE:To improve power transmission efficiency remarkably by a method wherein small diametral friction disks are pinched and pressed between a pair of large diametral friction disks and both of them are rotated by friction to transmit power. CONSTITUTION:The first small diametral friction disk 20 is fitted to the spline 9 of an input shaft 5 and the second small diametral friction disk 24 is attached rotatably to the proper place of a support shaft 10. The first large diametral friction disk 39 is fitted to the spline 15 of an output shaft 11 and the second large diametral friction disk 41 is engaged rotatably with the spline 19 of a pivot shaft 16, thus, the first and second small diametral friction disks 20, 24 are pinched between and held by the first and second large diametral friction disks 39, 41. According to this method, the power rotates the small diametral friction disks 20, 24 and the large diametral friction disks 39, 41 by friction and is transmitted while contacting condition between both disks becomes better and slip between them will never be generated. Accordingly, the power transmission efficiency may be improved remarkably.
