A hybrid driving module includes a housing and an axial movement prevention part configured to restrict forward and rearward movements of a rotor hub relative to the housing. The axial movement prevention part provided in a bearing interposed between the housing and the rotor hub. The bearing includes a first race configured to adjoin a first peripheral surface, a second race configured to adjoin a second peripheral surface, and rolling elements interposed between the first race and the second race. The axial movement prevention part includes a bearing groove provided in a surface of the first race, a circumferential surface groove provided in a first circumferential surface, and a clearance prevention ring inserted across the circumferential surface groove and the bearing groove. A height of the clearance prevention ring is equal to or smaller than a depth of the circumferential surface groove.
