Abstract: A driving device and a vehicle window lifter are disclosed. The driving device includes a motor and a gearbox. The motor includes a stator and a rotor. The gearbox includes a housing and a gear. The motor is mounted in the housing and includes a rotary shaft driving the gear. The housing supports the motor through a soft support structure. Two bearings are mounted in the housing at the same side of the stator for supporting and determining an orientation of the rotary shaft. Over-constraint to the rotary shaft is eliminated by reducing the number of the rigid support points between the rotary shaft and housing. The soft connection between the motor and housing can avoid or reduce motor vibrations transferred to the gearbox.
