An air blowing device adapted to be used in such a manner that at least two of the devices are horizontally and/or vertically aligned with each other, thereby to obtain a uniform flow of air in the downstream direction from device to device. An air-permeable front surface () is formed to the blowing device () at the downstream side of a rectifier mechanism, and side surface sections () which extend in the upstream direction of the device () are formed at both edges of the air-permeable front surface (). First ventilation holes () are distributed at the air-permeable front surface (), and second ventilation holes () are distributed at the side surface sections ().
