Disclosed is a driving module for a vehicle, comprising: a motor; a gear device installed on the motor; and a drive shaft interlocked with the gear device to be rotated. The motor comprises a motor housing, a stator, a rotor and a hollow motor shaft. The stator has a hollow shape and is installed on the interior of the motor housing. The rotor is rotatably positioned inside the stator. The hollow motor shaft has a hollow part passing through the drive shaft and allows the rotor to be installed thereon. An oil transfer part is formed on at least one of the hollow motor shaft and the drive shaft to induce oil in the direction of the gear device, the oil introduced between the inner periphery of the hollow motor shaft and the outer periphery of the drive shaft in the gear device. Oil of the gear device is prevented from leaking between the inner periphery of the hollow motor shaft and the outer periphery of the drive shaft. Moreover, damage to the interior of the motor, which can be caused when the oil passing between the inner periphery of the hollow motor shaft and the outer periphery of the drive shaft leaks into the interior of the motor, can be minimized. |
