Abstract

Disclosed are a sirocco fan whose noise level and rotational speed when the fan achieves a predetermined air volume are reduced and an air conditioner having the sirocco fan. The sirocco fan has a scroll (6), a fan body rotatably placed in the scroll (6) and having a large number of blades arranged in a circular tube-like form, and a motor for rotationally driving the fan body. The scroll (6) has two substantially parallel linear sections (12, 13) on the swirling outer form of the scroll. The rotating shaft of the motor is placed close to the linear section (12) that is near a tongue section (8) of the scroll.
