  • Torque transmission apparatus
    Patent number: 7458897
    Abstract: An apparatus for transmitting torque from a driving unit to a driven unit, comprising the first unit, the second unit and a plurality of torque transmission units. The first unit serves as the driving unit, which is rotatable around a central axis thereof. The second unit serving as the driven unit, which is rotatable around a central axis thereof. The torque transmission units transmits torque from the first unit to the second unit. The torque transmission units enables a relative displacement between the first unit and the second unit in a direction perpendicular to the central axis of the first unit in a state in which the central axes of the first and second units are kept in parallel with each other. The torque transmission units are placed at different positions from the central axis of the first unit.
