Zusammenfassung:To provide a blower device capable of improving air blowing efficiency.SOLUTION: A blower device includes a pair of fan parts, a housing part, and a lid part. The pair of fan parts generate an airflow on one side in the axial direction along a central axis, and are arranged coaxially. The housing part is formed in a cylindrical shape along the central axis, stores the pair of fan parts, and has open axial end surfaces. The lid part covers the corresponding one of one end surface in the axial direction and the other end surface in the axial direction of the housing part, and ventilates. Each of the pair of fan parts is fixed to the corresponding lid part, and has a motor for rotating an impeller. The impeller includes an impeller cylinder part, an impeller lid part, and a blade part. The impeller cylinder part is arranged outside in the radial direction of the motor, and extends in the axial direction. The impeller lid part covers an end surface in the axial direction of the impeller cylinder part, on the opposite side in the axial direction from the lid part where the motor is fixed. The plurality of blade parts are arrayed in the circumferential direction on an outer surface in the radial direction of the impeller cylinder part. In the pair of fan parts, the respective impeller lid parts directly face with each other in the axial direction.SELECTED DRAWING: Figure 4 【課題】送風効率を向上できる送風装置を提供する。【解決手段】一対のファン部とハウジング部と蓋部とを備える。一対のファン部は、中心軸に沿って軸方向一方側に気流を発生させ、同軸に配置される。ハウジング部は、中心軸に沿って筒状に形成されるとともに、一対のファン部を収容し、軸方向の両端面が開口する。蓋部は、ハウジング部の軸方向一端面及び軸方向他端面をそれぞれ覆い、通気する。一対のファン部は、蓋部にそれぞれ固定されるとともに、インペラを回転させるモータを有する。インペラは、インペラ筒部と、インペラ蓋部と、羽根部と、を有する。インペラ筒部は、モータの径方向外側に配置されて軸方向に延びる。インペラ蓋部は、モータが固定された蓋部と軸方向反対側において、インペラ筒部の軸方向端面を覆う。羽根部は、インペラ筒部の径方向外面において周方向に複数配列される。一対のファン部は、各インペラ蓋部が軸方向に直接対向する【選択図】図4
