Abstract

The present invention relates to a motor assembly comprising: a housing; a motor that is received at one side inside the housing in the axial direction; a gear train that is provided at the other side inside the housing in the axial direction; oil that is received inside the housing to be in contact with the gear train; and an oil storage unit that temporarily receives the oil moving upward when the gear train rotates, wherein the oil storage unit includes an oil outlet formed to discharge the oil received therein in a preset amount. Accordingly, the rotational resistance can be suppressed from increasing due to the oil received therein, and the oil can be continuously supplied (scattered) upward in a preset amount, and thus, continuous cooling can be achieved.
