A STEPLESS VARIABLE SPEED DRIVE ABSTRACT of the DISCLOSURE The variable speed drive comprises a driving shaft and a driven shaft coupled by a friction disk assembly, and is accommodated by a fixed case affording passage and support to the driven shaft, and a cover, adjustable for position in relation to the fixed case and affording passage and support to the driving shaft; the gap between the adjustable cover and the case is bridged by an impermeable boot-type seal anchored at its inner and outer edges in a fluid-tight fit to the cover and the case, respectively, and capable of flexing at least radially in relation to the two shafts. The cover incorporates a boss extending through the open center of the boot seal into the case and engaging with rods by which movement of the cover is guided, and to advantage, the seal is pleated with looped corrugations spreading out around the boss. fig 1
