かつた。<Prior art> Conventionally, in the case of this type of fan, the blades were pressed one by one and then assembled into plates for holding the blades on both sides to form a cylindrical fan, or the blades were pressed into a cylindrical fan. A predetermined number of wing pieces are punched out and formed into a cylindrical shape, and held from both sides by plates as described above, but in both cases, the relationship between the wing pieces and the plates not only takes time to assemble, but also requires uniformity. It lacked character and was not suitable for mass production.

ンを得んとしたものである。<Problems to be solved by the invention> Based on the above, it is necessary to use a required number of connected blades instead of one blade, form them into a cylindrical shape, and form an annular frame and a cap shape from both sides. The objective is to obtain an ideal cylindrical multi-blade fan with a simple structure that involves screwing the side plates.

ものである。<Means for solving the problem> Based on the above, the present invention will be explained with reference to the drawings which are examples. A metal wing piece 2 which is continuously formed with connecting parts 1 on both sides is rolled into a cylindrical shape, and the connecting parts 1 are 1 is provided with a plurality of notches 3 at equal intervals, and a ring 5 with screws 4 provided at the same intervals and in the same number as the notches 3 provided in the connecting part is fitted from the inside into the notches. Then, the screw 4 of the ring is made to protrude from the notch 3, and the side plate 8, which is integrally provided with a threaded annular frame 6 made of synthetic resin on one side and a support shaft 7 on the other side, is screwed in from both sides. It is a cylindrical multi-blade fan constructed by attaching the blades to the connecting part of the blades and the screws 4 by means of the annular frame 6 and side plates on both sides.
The wing pieces are fixed by sandwiching the attached ring.

ある。<Effects of the Invention> In the present invention, as described above, the metal wing piece 2 is rolled up into a cylindrical shape by continuous forming, and a plurality of notches 3 are provided at arbitrary equal intervals in the connecting part 1 on both sides of the wing. The threaded part 4 of a ring 5, which is provided from the inside at equal intervals with the notched part, is fitted into the notched part so that it protrudes from the notched part 3 by the thread height, and a synthetic resin annular frame 6 is fitted onto this. A cylindrical multi-blade fan is constructed by screwing a side plate 8 having a rotating support shaft 7 on one side and a rotating support shaft 7 on the other side.
Or, since there is no need to insert and swage the blades into the blade fitting grooves provided on the side plate, the required number of blades are connected with a portion left on both sides, so it can be formed into a single cylindrical shape by simply rolling it. Not only is this easy to do, but it is completed by screwing the annular frame 6 and the side plates 8 for assembly on both sides, so the fabrication is often easy, and the annular frame and side plates are made of plastic synthetic resin. Because it is made of aluminum, it has various effects such as being able to extremely absorb and reduce the noise generated when the blades rotate.
