Abstract

PURPOSE: To obtain a cup-type stepless speed change gear which is compact and easy to be installed onto the engine mounted on a vehicle or the like by allowing input and output shafts inserted each other to be supported relatively rotatably, having bearings installed between both shafts.
CONSTITUTION: On the input shaft 16 which is fixed on a driving shaft 12 by bolts 18, the flange part 20 and the driving cone supporting part 22 are formed, and a driving cone 24 is inserted into the supporting part 22. Oppositely to the driving cone 24, a driven cone 32 is arranged, and said cone 32 is installed on the output shaft 34 which is supported rotatably on the input shaft 16 by bearing 60 and 62. By these cones 24 and 32, a plurality of drive balls 44 are supported from one end. The drive ball 44 is supported rotatably through the spindle 46 of which both ends are supported by the circular holding grooves 48A and 48A of a housing 48, and the spindle 46 can be tilted through a speed change control plate 52 by the revolution of a worm 56.
