Abstract
An in-wheel motor system having a flexible coupling for transmitting the drive torque of a motor to a wheel. The flexible couplingsimple in structure and easily assembled comprises a motor-side plate (A) mounted to the rotating side case of the motor, a wheel-side plate (C) mounted to the wheel or a hub, an intermediate plate (B) disposed between these two plates (A) and (C), a first rubber member () of generally rectangular shape in plan view which connects the motor-side plate (A) to the intermediate plate (B) in such a manner that they can move relative to each other in a direction (direction B) orthogonal to their connection direction (direction A), and a second rubber member () formed in the same manner as the first rubber member () which connects the intermediate plate (B) to the wheel side plate (C) in such a manner that they can move relative to each other in the direction A orthogonal to the direction B.
