To prevent noise and vibration from being generated caused by drive- connection of a sun roller as an input member and a transmission shaft, in a planetary roller-type transmission.
In the planetary roller-type transmission, a sun roller 31 is formed into a cylindrical shape, and a cylindrical elastic member 30 is press- fitted in the inner peripheral surface 31a. A fitting hole 30a of the elastic member 30 is taken as a torque transmission surface, a rotary shaft 2a of a motor is press-fitted in it and drive-connected. Clearances between the elastic member 30 and the sun roller 31 and between the elastic member 30 and the rotary shaft 2a are eliminated. Therefore, inclination and eccentricity between the sun roller 31 and the rotary shaft 2a can be absorbed by the elastic member 30, moreover, vibration and noise can be prevented. Therefore, assembling costs and costs of parts can be reduced.
