PURPOSE: An in-wheel drive device is provided to increase driving torque while reducing the size of a wheel. CONSTITUTION: An in-wheel drive device(1) comprises a motor unit(10), a first deceleration unit(20), a second deceleration unit(30), a hub outer race(50), an hub inner race(52), and a wheel member(90). The first deceleration unit decelerates the driving shaft(17) of a motor unit. The second deceleration unit comprises a driving gear(36) and a driven gear(38). The driving gear is connected to the first deceleration unit. The driven gear is installed along the outer surface of the hub outer race. The hub inner race supports the hub outer race to be rotated. The hub inner race is installed in a housing(80). The wheel member is rotated with the hub outer race. |
