PROBLEM TO BE SOLVED: To provide a blower which inhibits water dropped to the outer side of a suction port of a fan casing from flowing to a motor through a cooling air intake passage for motor cooling.SOLUTION: A blower includes: a fan casing 52; a fan housed in the fan casing 52; a motor; a cooling air intake passage 70 communicating with a passage leading to the motor; and a communication passage 61 communicating with a peripheral passage 60 at the outside of the fan casing 52. The cooling air intake passage 70 and the communication passage 61 are passages penetrating through the fan casing 52. The communication passage 61 is a passage isolated from the cooling air intake passage 70 and positioned at a downstream side of the cooling air intake passage 70 in an airflow direction.SELECTED DRAWING: Figure 3

    【課題】ファンケーシングの吸込口の外側に落下した水がモータ冷却用の冷却風取込通路を通じてモータへ流れることを抑制できる送風装置を提供する。【解決手段】送風装置は、ファンケーシング52と、ファンケーシング52に収容されるファンと、モータと、モータに通じる通路に連通する冷却風取込通路70と、ファンケーシング52の外側の周囲通路60に連通する連絡通路61と、を備える。冷却風取込通路70と連絡通路61とは、ファンケーシング52を貫通して設けられる通路である。連絡通路61は、冷却風取込通路70とは隔てられた通路であり、冷却風取込通路70よりも空気流れの下流に位置する。【選択図】図3
