A variable pulley transmission in which each pulley is constructed of a pair of flanges coupled to respective shafts, at least one flange of each pair being axially movable relative to the other flange of the same pair, the movable flange being coupled to its shaft by an external spline operative associated with the flange meshing with an internal spline on {HEAD ~ a drive member} coupled to {TAIL ~ the shaft}
