The invention relates to a drive unit and a cover of the drive unit, which can effectively discharge water inside the cover of the drive unit. A drive unit (10) is provided with: a motor (3); a housing (1) that holds the motor (3) and is attachable to a vehicle; and a cover (2). The cover (2) comprises: a bottom part (2B) covering at least a part of the lower surface of the housing (1) from below; and a left side wall (2L) extending from the bottom (2B) and covering at least a part of the left side of the housing (1). The cover (2) has a first hole (2a) provided in at least one of a left side wall (2L) and a portion of a bottom portion (2B) that is on the left side of the center in the left-right direction of the vehicle. When a vehicle to which the housing (1) is mounted is tilted leftwards by 5 degrees from an upright state, at least a part of the edge (2af) of the first hole (2a) on the cover inner side is at a position that is lowest in the gravitational direction on the cover inner surface (2n).
