Title: ELECTRIC VEHICLE DRIVE DEVICE
Abstract:
Provided is an electric vehicle drive device capable of shortening the length of a speed reducer in the vehicle front-rear direction without complicating the configuration thereof. A motorcycle 100 drive device is equipped with a chassis frame 30, a rear wheel 20, a swing arm 41 supported by the chassis frame 30 so as to be capable of oscillating, a drive motor 10 configured separately from the rear wheel 20, and a speed reducer 50 which reduces the speed of the motive force outputted from an output shaft 11 of a drive motor 10, and transmits the same to the rear wheel 20. Therein, the speed reducer 50 is equipped with a final shaft 52 which is coupled to the rear wheel 20 and transmits motive force from the motor output shaft 11 via an idle shaft 51, and also equipped with a speed reducer case 60 for covering at least part of the idle shaft 51 and final shaft 52 when seen from a lateral surface view. When seen from the lateral surface view, the motor output shaft 11 and the final shaft 52 overlap one another.
