PROBLEM TO BE SOLVED: To provide an in-wheel motor driving device excellent in silence and durability.SOLUTION: An in-wheel motor driving device 21 comprises a casing 22 holding a motor part A, a deceleration part B, and a wheel bearing part C. The motor part A comprises a stator 23a fixed to the casing 22, a motor rotating shaft 24 rotatably supported by the casing 22 via rolling bearings 36 and 36, and a rotor 23b fitted to the motor rotating shaft 24. The rolling bearings 36 have a radial inside gap δ set to 8-25 μm before incorporation into the motor part A.SELECTED DRAWING: Figure 5
