Hybrid driving module

A hybrid driving module, which has a motor including a rotor and a stator, the hybrid driving module comprising:

• a housing in which the stator is installed;
• a rotor hub on which the rotor is installed, the rotor hub being configured to be rotatably supported by the housing;
• and
• an axial movement prevention part configured to restrict forward and rearward movements of the rotor hub relative to the housing between the housing and the rotor hub,
• wherein the axial movement prevention part is provided in a bearing or interposed between the housing and the rotor hub and configured to support a rotation of the rotor hub relative to the housing,
• wherein the bearing is interposed between a peripheral surface at a side of the housing and a peripheral surface at a side of the rotor hub that face each other in a radial direction,
• wherein the bearing comprises:
• a first race configured to adjoin a first peripheral surface that is one surface selected from the peripheral surface at the side of the housing and the peripheral surface at the side of the rotor hub;
• a second race configured to adjoin a second peripheral surface that is the other surface selected from the peripheral surface at the side of the housing and the peripheral surface at the side of the rotor hub;
• and
• a rolling element interposed between the first race and the second race, and wherein the axial movement prevention part comprises:
• a bearing groove provided in a surface of the first race facing the first peripheral surface;
• a peripheral surface groove provided in the first peripheral surface and disposed at a position corresponding to the bearing groove;
• and
• a clearance prevention ring inserted across the peripheral surface groove and the bearing groove.
