IN-WHEEL MOTOR DRIVING DEVICE AND CONNECTION STRUCTURE OF IN-WHEEL MOTOR DRIVING DEVICE AND WHEEL

摘要

PROBLEM TO BE SOLVED: To provide an in-wheel motor driving device which enables a connection portion between an in-wheel motor and a vehicle body side member to be located closer to an axis of a wheel than conventional in-wheel motor driving devices.;SOLUTION: A casing (43) of an in-wheel motor driving device (10) includes: a cylindrical body first casing (43g) disposed at one side in an axis (O) direction; and a cylindrical body second casing (43a) disposed at the other side in the axis direction. The body first casing and the body second casing respectively have annular butted parts (43j) butted with each other in the axis direction. A hub carrier (18) has a connection part (82s) for rotatably connecting to a vehicle body side member (81) at a tip. An axial position of the connection part is arranged so as not to overlap with an axial position of the butted surface and so as to overlap with an axial position of the body first casing or the body second casing.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
