<P>PROBLEM TO BE SOLVED: To provide an in-wheel motor in which the coaxial accuracy of a pair of fixed axes projected from both right and left sides of a hub is improved to suppress vibration, abnormal sounds, and noise from being generated, thereby contributing to improvement in ride quality. <P>SOLUTION: The in-wheel motor 10 includes: the hub 12; a first fixed axis member 20 penetrating one surface side of the hub 12 and rotatably supporting the hub 12; a second fixed axis member 24 penetrating the other surface side of the hub 12 coaxially with the first fixed axis member 20 and rotatably supporting the hub 12; a motor 26 disposed in the hub 12; a reduction mechanism 28 having a through hole 66a coaxially with the second fixed axis member 24 and reducing the rotation speed of a rotor core 52; an internal gear 46 which is fixed to an inner periphery of the hub 12, and to which an output gear of the reduction mechanism 28 is connected; and a third fixed axis member 40 for coupling the first fixed axis member 20 with the second fixed axis member 24 via the through hole 66a on axis lines thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
