Abstract
A motor unit includes a case, a motor, an input shaft, an input body, an output body, and a speed reducer mechanism. The input shaft penetrates through the case in an axial direction and is arranged to be rotatable. The input body is disposed along an outer peripheral surface of the input shaft and rotates along with the input shaft. The output body is arranged along the outer peripheral surface of the input shaft to be rotatable and receives rotational force from the input body. The case includes a first bearing, a second bearing, and a third bearing. The first bearing is located at one end in an axial direction and supports a rotary shaft unit including the input shaft, the input body, and the output body. The second bearing is located at the other end in the axial direction and supports the rotary shaft unit. The third bearing is located between the first bearing and the second bearing in the axial direction and supports at least one of the input body or the output body.
