A drive unit includes a decelerator rotatably supported by a housing, the decelerator including a first transmission gear, a second transmission gear having teeth of a smaller number than that of the first transmission gear, and a transmission shaft to transmit a rotation of the first transmission gear to the second transmission gear; and a bearing supporting the first transmission gear in the housing such that the first transmission gear is rotatable. A distance, in a first direction in which the transmission shaft extends in the housing, from a reference plane to teeth of the first transmission gear is less than a distance in the first direction from the reference plane to an innermost portion of the bearing, in which the reference plane passes through an outermost portion of the bearing and is perpendicular to the first direction.
