PROBLEM TO BE SOLVED: To provide a highly durable wheel supporting device for solving the problem that a motor is rotated by a rotation of a wheel, a shearing force is applied to a motor support section by the rotation of the motor, and the durability of the motor support section decreases. SOLUTION: The wheel supporting device 200 comprises motor mounts 140 and 150, ball joints 160 and 170, a knuckle 180, a torque rod 190, a member 194, an upper arm 210, and a lower arm 220. The motor mounts 140 and 150 support an in-wheel motor IWM to be swingable in the vertical direction DR 1 of the vehicle body. The motor mount 140, the knuckle 180, and the upper arm 210 are connected to the ball joint 160, and the motor mount 150, the knuckle 180, and the lower arm 220 are connected to the ball joint 170. The knuckle 180 rotatably supports a wheel hub 20 via hub bearings 11 and 12. The torque rod 190 is connected to the ball joint 160, and penetrates the member 194 fixed to an end surface 60A of a case 60. COPYRIGHT: (C)2005,JPO&NCIPI
