Abstract
A motor assembly includes a housing, a first substrate, a plate-shaped second substrate, and a connector portion. The housing includes a tubular portion that accommodates a motor with an axis of rotation that extends in the vertical direction. The first substrate extends in a direction perpendicular to the axial direction. The second substrate extends in a direction intersecting the first substrate. The connector portion electrically connects the first substrate and the second substrate. The connector portion overlaps with the housing as viewed from the axial direction.
