A disk bevel gear(5) is fixed at a power leading shaft(1) that perforates into both side panels(2a and 2b), and engages with plural fixation disk friction plates(7a, 7b, 7c). A working disk friction plate(17) is mounted in an inner space(4) formed by the respective fixation disk friction plates(7a, 7b, 7c), vertically with respect to the friction plates(7a, 7b, 7c). The friction wagons(7a, 7b, 7c) are pressed elastically by plate springs(14a, 14b, 14c), to make a circumferential face of the rotary disk friction plate(17) contact with the surfaces of the respective fixation disk friction plates(7a, 7b, 7c) under a uniform force. The working disk friction plate(17) is coupled with an output shaft(18) by a spline, and an output gear(19) transmits a power outside.
