PURPOSE:To prevent the generation of backlash by utilizing the rotational directionality of a roller and the inclination so as to generate a frictional transmitting force and thereby removing stress deformation from the essential part of each member. CONSTITUTION:If A rotor 1 or B rotor 2 rotates in the arrow direction, a roller 3 is also applied with rotational force in the arrow direction. Since the direction of this rotation is rotational direction toward narrower space between a inclined part 5 and a track part 4 and high inclination, simple frictional transmitting force is generated and the A rotor 1 and the B rotor 2 are directly coupled, transmitting force. If A rotor 1 or B rotor 2 rotates in the opposite direction, the roller 3 also rotates itself in the direction where the frictional transmitting force doesn't occur and the rotors 1, 2 idle. Accordingly, the frictional transmission is generated in the rotational transmission system and the inclined part 5 becomes inclinations whose differences are equal, therefore stress deformation is not generated in the member and backlash can be prevented. |
