PURPOSE: A drag torque shielding double synchro-gear assembly is provided to prevent friction force transferring for a drag torque from generated in a neutral state by maintaining separation between gears which form ring with a hub. CONSTITUTION: A drag torque shielding double synchro gear assembly comprises: a synchro gear which includes an inner ring(1), a middle ring(2), and an outer ring(3) which are successively and integrally combined each other; and a hub(4) which comprises an insertion assembly step(5) with a leveled surface in order to form a non-contacted interval with the inner ring, the middle ring, and the outer ring.
