Abstract

A motor unit includes a motor including a shaft to rotate about a motor axis, and a stator, a reduction gear, and a housing. The shaft includes a first shaft portion, a connecting shaft portion, and a second shaft portion arranged coaxially with one another, and a separating mechanism between the connecting shaft portion and the second shaft portion. The first shaft portion includes a first end portion. The connecting shaft portion includes a second end portion coupled to the first end portion, a third end portion located on a side opposite to the second end portion, and a connection flange portion extending radially outward. The second shaft portion includes a fourth end portion. The separating mechanism selectively separates the connection flange portion and the fourth end portion from each other.
