Patent ID: 8857545

Claim:
An in-wheel drive apparatus comprising: a motor housing open at one side thereof; a motor unit mounted within the motor housing, the motor unit comprising: a stator disposed along an inner peripheral surface of the motor housing; and a rotor rotatably disposed inside the stator, the rotor comprising a rotor shaft placed at a center of the motor housing, a magnet mounting section formed on an outer peripheral surface of the rotor and having a magnet mounted thereon to face the stator, and a connection plate interposed between the rotor shaft and the magnet mounting section and connecting the rotor shaft to the magnet mounting section, wherein a lower portion of the connection plate protrudes leftwards and an upper portion of the connection plate protrudes rightwards to create a cavity such that a cover recess of a rear cover protrudes rightwards into the cavity created; and wherein the rear cover is coupled at one side thereof to the motor housing to close the open side of the motor housing and at the other side thereof to a trailing arm, the rear cover comprising: a planar section constituting an outer peripheral surface of the rear cover; and the cover recess connected to an inner peripheral surface of the planar section to be integrally formed with the planar section and depressed from the planar section towards the rotor to form a recess to which the trailing arm is coupled.
