Abstract

The object of the present invention is to provide compact toroidal type continuously variable transmission for a front engine front wheel drive vehicle, which employs geared neutral starting system. The toroidal type continuously variable transmission according to the present invention comprises an input shaft 11 whose one end is coupled with an engine, a primary shaft 12 into which said input shaft is fittingly inserted with play, a secondary shaft 13 which is disposed parallel with said shafts and whose engine side end is coupled with a differential gear unit 5, toroidal type continuously variable transmission mechanisms 20, 30 which are disposed on said primary shaft 12, a planetary gear mechanism 50 which is disposed on said secondary shaft 13, a low mode gear train 80 for coupling the input shaft 11 with a carrier 51 of the planetary gear mechanism 50, and a high mode gear train 90 for coupling a sun gear 52 with an output disk 34 of the continuously variable transmission mechanisms 20, 30, wherein said low mode gear train 80 is disposed on an opposite side end, with respect to the engine, of the input shaft 11.
