<P>PROBLEM TO BE SOLVED: To provide an in-wheel motor driving device that enables highly accurate alignment between a central shaft of a wheel and an output shaft of the in-wheel motor driving device, thereby preventing vibration and noise while improving durability. <P>SOLUTION: This in-wheel motor driving device 1 is installed inside a wheel 100 of a wheel 200 rotatably supported via a hub bearing 52 supported by a support part 95 of a suspension device 90, and drives the wheel 200 by a motor 3 stored in a case 2. In this case 2, a spigot fitting surface 2Ac arranged axially parallel to a centering surface 52Ab and to be fitted by a spigot, is formed in a fitting hole 95a of the support part 95 of the suspension device 90 to be fitted by the spigot to the centering surface 52Ab formed in a concentrically circular shape with the rotational center of the output shaft 50 and formed on an outer peripheral surface of a bearing case 52A of the hub bearing 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
