Title:
MOTOR DRIVE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/006716
Kind Code:
A1
Abstract:
A speed-reducing part has a speed-reducing part input shaft (25), a speed-reducing part output shaft (28), a first rolling bearing (39) and second rolling bearing (38) for rotatably supporting both axial-direction end sides of a shaft body of at least one of the speed-reducing part input shaft and the speed-reducing part output shaft, and a bearing precompression means for imparting axial precompression to the first rolling bearing and the second rolling bearing. The bearing precompression means is characterized in that precompression is imparted by inner race retainers (48, 49) and a precompression spring (66) in the direction in which an inner race (39p) and an inner race (38p) move towards each other, while the axial-direction positions of an outer race (39q) and an outer race (38q) are regulated by outer race retainers (46, 47).
