PROBLEM TO BE SOLVED: To provide a multi-disc reduction gear which can transmit high torque.SOLUTION: A multi-disc reduction gear 3 comprises a pair of pressing means 13 which grip and press an input disc 11 and an output disc 12, and form a torque transmission part. The input disc 11 or the output disc 12 with which the pressing means 13 contact is an arm-shaped curved disc 11a, an inclination angle of the curved disc 11a with respect to an input shaft 10 or an output shaft 14 is changeable, the curved disc 11a is movable to an axial direction, and attachment means 22 is provided which attaches the curved disc 11a to the input shaft 10 or the output shaft 14 so that the curved disc 11a becomes relatively non-rotatably with respect to the input shaft 10 or the output shaft 14. |
