Title: IN-WHEEL MOTOR DRIVE DEVICE
Abstract:
An in-wheel motor drive device (21) has: a motor section (A); a speed reducer section (B) constituted by a parallel shaft gear speed reducer (39) comprising a plurality of gears; a bearing section (C) for a wheel; and a rotary pump (60) for delivering lubricating oil under pressure. An intermediate shaft (S2) having intermediate gears (33, 34) is disposed between the input shaft (30a) of the speed reducer section (B) and an output shaft (36), and the intermediate shaft (S2) drives the rotary pump (60). The rotary pump (60) is disposed on the outer diameter side of the motor section (A) so as to radially overlap the motor section (A).
