Abstract: Construction of an electric automobile drive apparatus is realized in which the relationship of the traveling speed and acceleration of a vehicle can be made smooth and closer to the ideal, and the transmission efficiency can be maintained. A bypass gear-transmission mechanism 10, a toroidal continuously-variable transmission 11, a first planetary-gear mechanism 12 and a second planetary-gear mechanism 13 are arranged parallel to each other in the power transmission direction between a driving-side rotating shaft 4a that is the input shaft and a driven-side rotating shaft 5a that is the output section and that is arranged parallel to the driving-side rotating shaft 4a. A first clutch mechanism 16 is provided between the bypass gear-transmission mechanism 10 and the driven-side rotating shaft 5a, and a second clutch mechanism 44 and third clutch mechanism 49 are provided between the output gear 38 of the toroidal continuously-variable transmission 11 and first planetary-gear mechanism 12 and second planetary-gear mechanism 13.
