Provided is an airflow diffusion device (diffusion fan) which diffuses air current by means of the suction flow of an air conditioner. The airflow diffusion device is provided with: an impeller which comprises an air-current-receiving member for receiving air current sucked in through an air intake of an air conditioner, a diffusion member arranged at the outer circumferential side of the air-current-receiving member to diffuse air current blown out from an air vent of the air conditioner, and a hub member for supporting the air-current-receiving member and the diffusion member; a shaft member which constitutes a rotary shaft of the impeller; and an attachment member which supports the shaft member in a position in which the impeller is rotated by air current sucked in through the air intake of the air conditioner. |
