Abstract
A motor module includes a motor, a fan, and a casing accommodating the motor and the fan therein. The casing includes a tubular main body portion, an intake port, an exhaust port, a motor disposing unit, a flow passage, and a partition unit. The flow passage includes a fan accommodating unit. The partition unit includes a first central partition unit that partitions the fan accommodating unit and the motor disposing unit. The first central partition unit includes a cutout portion provided at at least a portion of the first central partition unit. The motor disposing unit communicates with the fan accommodating unit via the cutout portion. A flow passage sectional area of the motor disposing unit is greater than a flow passage sectional area of the first central partition unit.
