PURPOSE:To externally take out power from an input shaft by loosely fittingly inserting said input shaft which is coaxially provided with the output shaft of a differential planetary continuously variable transmission, into said output shaft and projecting it out of a transmission case. CONSTITUTION:An input disk 3 is connected in power to the flange part of an input shaft 1 by means of claw combination 15, and supported by an output shaft 2 and a transmission case 12 with bearings 16, 17. Power which is transmitted to an output disk 4 is transmitted to a drive wheel by means of a ball clutch mechanism 18, and to the output shaft 2. An advancing/reversing shift gear 22 is slidably while firmly fitted over the output shaft 2. This output shaft 2 is formed into a two-shaft structure consisting of an output shaft 2a over which the components of a transmission 10 is fitted and an output shaft 2b which is continuously and coaxially provided on its side by means of a claw combination 29, while the input shaft 1 is loosely fittingly inserted into the output shafts 2a, 2b. The end part of the input shaft 1 is projected out of the transmission case 12 and an appropriate power take-out mechanism 24 is provided on the projected end part. Thereby, power can be externally taken out of the input shaft.
