A blowing fan assembly for a window-type air conditioner which includes a scroll case and a turbofan disposed in the scroll case and connected with a driving motor, the turbofan having a hub, a plurality of blades which are located at a predetermined separation from the hub, and a shroud which is attached to distal ends of the plurality of blades in opposition to the hub. A depression is formed at the rear wall of the scroll case in a manner such that the diameter of the depression is greater than an outer diameter of the turbofan, and the turbofan is lop-sidedly positioned in the scroll case in such a way as to adjoin the depression, whereby the air passage which is defined between the shroud of the turbofan and a suction opening of the scroll case, is increased.
