Drive device and method for manufacturing drive device

A drive device according to one embodiment of the present invention is provided with: two geared motors each having a motor main body extending along a central axis and a pinion gear disposed on one side in the axial direction of the motor main body and rotating about the central axis by the motor main body; a rack engaged with the two pinions; and a frame that holds the two gear motors and the rack. The direction in which the central axes of the two gear motors are arranged is set as a first direction, and the direction perpendicular to the first direction and the central axes is set as a second direction. The size of the geared motor in the second direction is the largest at the motor body. The motor body protrudes from the frame toward both sides in the second direction. 本发明提供驱动装置以及驱动装置的制造方法，本发明的一个方式的驱动装置具有：2个齿轮传动马达，该2个齿轮传动马达具有沿着中心轴线延伸的马达主体和配置于马达主体的轴向一侧并且通过马达主体而绕中心轴线旋转的小齿轮；齿条，其与2个小齿轮啮合；以及框架，其保持2个齿轮传动马达和齿条。将2个齿轮传动马达的中心轴线排列的方向设为第1方向，将与第1方向和中心轴线垂直的方向设为第2方向。齿轮传动马达的第2方向上的尺寸在马达主体处最大。马达主体从框架向第2方向的两侧突出。
