Abstract
A transmission is adapted to have a deceleration structure while generating an output in the same direction as when a motive power is rotated forwardly when the motive power is rotated reversely. The transmission includes a motor, an output cover, fixed shafts, and a transmission. The transmission is selectively connected according to the rotational direction of the driving shaft. The transmission provides a constant speed output in the forward direction since the driving shaft and the output cover are directly connected to each other when the driving shaft is rotated forwardly, but provides a decelerated output in the forward direction since a reduction planetary gear is geared between the driving shaft and the output cover when the driving shaft is rotated reversely.
