Abstract:
Provided is a cross flow fan of which an internal stress is reduced without detracting from manufacturing efficiency. During the manufacture of the cross flow fan, fan components (1, 2, 3) are ultrasonically welded and assembled while being rotated around a fan rotating shaft. Application of force to the cross flow fan in an unwanted rotating direction for ultrasonic welding can be suppressed, making it possible to reduce an internal stress due to ultrasonic welding.
