PROBLEM TO BE SOLVED: To further improve road holding property by further improving a structure for allowing motor mass to operate as a weight for a dynamic damper, float-mounting an in-wheel motor to a vehicle unsprung part. SOLUTION: A rotation side case 3b of the in-wheel motor 3 and a wheel 2 are coupled by a flexible coupling 10, and a non-rotation side case 3a and a knuckle 5 are connected by a buffer 20 provided with two plates 24A, 24B joined by a spring 22 and a damper 23 with each operating direction being restricted in a vertical direction of a vehicle through a linear motion guide 21 for operating in the vertical direction of the vehicle. Further a brake disk 8a of a brake 8 is mounted to a motor side plate 11A of the flexible coupling 10, and a brake caliper 8b is arranged inside the brake disk 8a in a radial direction and mounted to a stator side plate 24A of th buffer 20.
