ABSTRACT:
A stepless or continuously variable automatic transmission for motor vehicles including a first shaft coupled with the output shaft of an engine and rotatably supported by the transmission case, a second shaft disposed parallel with the first shaft and supported by the transmission case rotatably at three support points, and a third shaft disposed parallel with the second shaft and rotatably supported by said transmission case, transmitting power from said first to second shaft by a V-belt type stepless transmission and from the second to third shaft by meshed engagement of an output gear mounted on the second shaft and an input gear mounted on the third shaft, said stepless automatic transmission being characterized in that: the second shaft is divided into an input section mounting an output pulley of said V-belt type stepless transmission and an output section mounting the output gear, one of the input and output sections being rotatably supported at one outer support point and an intermediate support point of the three support points and formed with an inner spline on the side of the intermediate support point while the other one of the input and output sections being rotatably supported at the other outer support point and formed with an outer spline on the side of the intermediate support point for fitting engagement with the inner spline.
