A blower device comprising:

• a pair of fans that generates an airflow on one side in an axial direction along a central axis, the pair of fans being coaxially arranged with respect to one another;
• a housing that has a tubular shape and extends along the central axis, the housing accommodating the pair of fans, two axial end surfaces of the housing being opened;
• and
• a lid that covers each of a first axial end surface and a second axial end surface of the housing, and provides ventilation;
• wherein
• the lid includes an annular portion that is in contact with an inner peripheral surface of the housing and includes a through hole penetrating in a radial direction;
• and
• the housing includes an engagement protrusion that protrudes radially inward from the inner peripheral surface and engages with a periphery of the through hole.
