PROBLEM TO BE SOLVED: To provide a structure to simply fix a blower consisting of a plurality of turbo-fans and stationary blade fans. SOLUTION: The blower is structured so that two or more fans are arranged furnished with an impeller and a housing having a cylindrical portion to accommodate the impeller rotatably, wherein a flat surface is formed on each of the parts of the fan where the housings are facing. Among the two flat surfaces, the one flat surface where one turbo-fan confronting the other turbo-fan is furnished with a projection being directed to where the other turbo-fans are arranged in row, while the other flat surface is provided with a notch recessed or cut off. The first named flat surface contacts with the other flat surface, and they are rotated in sliding in certain rotating directions relative to each other centering on a point decided on either flat surface.
