ABSTRACT:
A device for reducing torque variations for use in a drive apparatus which has a drive shaft for causing a lift unit to perform one cycle of up-and-down movement for each of at least two lift units to perform one cycle of up-and-down movement at a specified interval by one turn of rotation of the drive shaft. The device comprises elastic means and transmission means for transmitting an elastic force of the elastic means to the drive shaft as a rotational torque.
