Summary:To improve cooling performance of a motor and inhibit entry of water into the motor to prevent a failure from occurring in the motor in a blower device having two laminar flow, i.e., inner and outer airflow.SOLUTION: A casing 8 is provided with a cooling air passage 70 which supplies cooling air to a motor which drives a fan. An upstream end of the cooling air passage 70 communicates with an upper layer air passage 17.SELECTED DRAWING: Figure 4 【課題】内外気２層流の送風装置において、モーターの冷却性能を向上させるとともに、モーターへの水の浸入を抑制してモーターに不具合が発生しないようにする。【解決手段】ケーシング８にはファンを駆動するモーターに冷却風を供給する冷却風通路７０が設けられている。冷却風通路７０の上流端が上層空気通路１７に連通している。【選択図】図４
