An object of the invention is to always maintain an outer pin holder and a housing in a speed reducer section at their predetermined positions, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, etc., and to eliminate rattling noise caused by the housing and the outer pin holder. A casing immobilizing member which is fixed to an inner surface of a speed reducer section casing and a housing immobilizing member which is fixed to an outer surface of a speed reducer section housing are provided between the speed reducer section casing and the speed reducer section housing. The casing immobilizing member and the housing immobilizing member are bonded with each other via a rubber member.

Mode selection of an electrically motorized vehicle

An in-wheel motor drive unit ( 21 ) includes a motor portion A, a speed reduction portion B, and a wheel hub C. The speed reduction portion B includes outer pins ( 27 ) engaging with circumferences of curve plates ( 26 a ) and ( 26 b ) to generate rotation movements of the curved plates, and an outer pin holding portion ( 45 ) fixedly fitted in an inner diameter surface of a casing ( 22 ) holding the speed reduction portion B, to hold the outer pins ( 27 ) parallel to a rotation axis of a motor side rotation member ( 25 ). The outer pin holding portion ( 45 ) includes a cylindrical portion ( 46 ), a pair of ring portions ( 47 ) and ( 48 ) extending from axial both ends of the cylindrical portion ( 46 ) to radially inner side, and a pair of outer pin holding holes ( 47 a ) and ( 48 a ) provided at opposed positions of the pair of ring portions ( 47 ) and ( 48 ), and extending parallel to the rotation axis of the motor side rotation member ( 25 ) to hold the axial ends of the outer pin ( 27 ).

In-wheel motor drive unit

An object of the present invention is to reduce an axial dimension of an in-wheel motor driving device in which a motor section A and a wheel hub bearing section C are connected coaxially in series via a speed reducer section B, thereby providing a large inside space of a vehicle as well as increasing freedom of routing a power supply wires. A terminal box for the power supply wires which supply power to the motor section A is disposed on the outer circumferential side surface of the housing which holds the motor section A. The power supply wires are routed out of the terminal box to an inboard side and are anchored by a power supply wire holder which extends perpendicularly to an axial centerline of the housing.

In-wheel motor-driven device

In a configuration where a left and a right wheels are driven individually by a plurality of drive-motor units mounted on a vehicle body, power transmission members which are provided by constant-velocity joints have a small operation angle made by their input shafts and output shafts for improved life of the constant-velocity joints. Left and right wheels are individually driven by a plurality of drive-motor units, which are mounted onto a vehicle body via a sub-frame, so that each power transmission member provided by a constant-velocity joint has a small operation angle made by its input shaft and output shaft.
