PROBLEM TO BE SOLVED: To prevent intrusion of a foreign matter to a gap part between a motor rotor and a wheel by a simple method in an in-wheel motor system having a constitution that a motor is operated as a dynamic damper. SOLUTION: In the in-wheel motor system having a constitution that a stator side case 3a for supporting a stator 3S of an in-wheel motor 3 is supported to a knuckle 5 through a shock-absorbing mechanism 10, an air tube 30 is inserted to the gap part of a rotor side case 3b and the wheel 2 and air is filled in the air tube 30 at a predetermined pressure to close the gap part by the air tube 30. The air tube 30 is fixed to the rotor side case 3b. COPYRIGHT: (C)2006,JPO&NCIPI
