Abstract
A gear mechanism comprises a housing, an input gear of helical gear supported by the housing for rotation in first and second rotational directions and adapted to be connected to a rotational power source, an output gear of a helical gear supported by the housing for rotation, a first gear train for transmitting the rotational power from the input gear to the output gear when the input gear rotates in the first rotational direction, a second gear train for transmitting the rotational power from the input gear to the output gear when the input gear rotates in the second rotational direction.
