[Problem] To provide a cross-flow fan having excellent ease of balance adjustment, low cost, high precision, high rigidity, and a high degree of silence without the need for an ultrasonic welding step, and to provide a method for manufacturing the cross-flow fan. [Solution] This method comprises: a first step of injection-molding a plurality of double fans made of resin and configured according to a cross-flow scheme, having a bearing portion and a fixed portion in a central wall; a second step of fabricating a connecting shaft corresponding to the desired fan length; a third step of inserting the connecting shaft fabricated in the second step into the bearing portion of the double fans molded in the first step; a fourth step of fixing the connecting shaft and the fixing portion using an engaging fixture; a fifth step of repeating the third and fourth steps to obtain the desired fan length; and a sixth step of adjusting balance as needed. |
