Disclosed is a speed reduction device for a vehicle motor. The speed reduction device includes an output gear connected to an output shaft of the motor, a transmission gear engaged with the output gear, a cam formed to be integrated with the transmission gear, a cycloid inner gear, a pair of wedges compressed against the inner peripheral surface of a through hole of the cycloid inner gear by elastic restoring force of a spring and configured to closely contact the cam, a ring gear partially engaged with the cycloid inner gear when the cycloid inner gear is eccentrically rotated, an end plate, and a final output gear configured to finally output rotational force of the cycloid inner gear, thereby preventing backlash between gears during rotational driving of the motor and reliably preventing movement of a seat after swivel adjustment is completed.
