PROBLEM TO BE SOLVED: To provide a hybrid car having high stability by reducing the unspring weight. SOLUTION: The hybrid car comprises front wheels as steering wheels, rear wheels as driving wheels, and an in-wheel motor driving device for transmitting the driving force to the right and left rear wheels. The in-wheel motor driving device comprises a motor unit A for generating the driving force, a deceleration unit B for providing the unit by decelerating the rotation of the motor unit A, and a wheel hub bearing unit C for transmitting the output from the deceleration unit B to the driving wheels 34. The deceleration unit B comprises curved plates 12a, 12b to be rotatably held by eccentric parts 2a, 2b, a plurality of outer pins 14 which are held at fixed positions on a casing 11a and engaged with outer circumferential portions of the curved plates 12a, 12b, and a motion conversion mechanism for transmitting the rotating motions of the curved plates 12a, 12b to an output member 15.
