ABSTRACT:
A transmission device having a simplified construction as well as a higher power transmission efficiency is provided, wherein a rotational speed can be changed steplessly without interrupting a power transmission and the rotation can be reversed. In the outer periphery of the rotating shaft (2) a thread-shape spline (5) having a first inclined plane oblique to the axial direction is provided and a rotating body (3) having a spline (not-shown) engaging with the spline (5) is rotatably and externally engaged with the rotating shaft (2). One of the rotating shaft (2) or the rotating body (3) is selected as a driving side and the other is selected as a driven side and both or one of the rotating shaft (2) and the rotating body (3) are displaced in the axial direction of the rotating shaft (2). By changing the relative speed and direction of displacement between the rotating shaft and the rotating body at their displacement, a rotation of constant speed can be transmitted into the driven side at a speed changed steplessly in a possible range or in a reverse direction.
