摘要:
A vehicle drive unit (11) includes a spindle (12) on which a female spline portion (12G) is formed, a wheel (15) disposed on an outer peripheral side of the spindle (12), wheel bearings 17, 18 that rotatably support the wheel (15) in relation to the spindle (12), an electric motor (21) located on an axial one side of the spindle (12), a shaft (22) connected to an output shaft (21B) of the electric motor (21), a planetary gear reduction device (25) disposed between the shaft (22) and the wheel (15), and a shaft bearing (46) that rotatably supports the shaft (22) in relation to the spindle (12). A retainer (42) retaining the shaft bearing (46) is disposed on an inner peripheral surface side of the spindle (12), and a male spline portion (42E), which is spline-coupled to a female spline portion (12G) of the spindle (12), is disposed on the retainer (42).
