合構造を提案せんとするものである。However, in the method of connecting the metal plates as described above, for example, in the method shown in FIG. 6, a folding margin for bending the side plate 21 to the guide plate 22 side is provided. Since it is necessary, there is a problem that an extra material is required for that amount, a welding man-hour is required, and a welding burr easily appears, and it is difficult to remove the burr. Further, the welding work is expensive, which results in an increase in product unit price. Further, in the method shown in FIG. 8, although the processing cost is lower than that of welding, a part of the protruding portion of the guide plate may protrude (see t in the drawing) from the side plate after the product is completed, or may protrude. There is a corner on the protruding part, so workers may be injured in the post process of assembling other products using this centrifugal blower,
There were some problems such as the appearance not being good. In view of the above problems, the present invention proposes a method and structure for joining metal plates, which has a low processing cost, a good appearance, and a high safety.

なる例示に過ぎず、限定的に解釈してはならない。According to the present invention, the metal plates can be efficiently joined together as described above. Therefore, if this joining structure is applied to the casing of a centrifugal blower, the processing cost can be reduced. Furthermore, since the protrusion of the guide plate does not protrude from the surface of the side plate, it is possible to prevent injury when handling the casing. Further, although the present embodiment has described the connection between the side plate and the guide plate of the casing of the blower, the present invention can be applied to, for example, the connection portion of various metal plates including the connection between the blade and the ring of the fan of the blower. In particular, when the present invention is applied to the connecting portion between the fan blade (first metal plate) 10 and the ring 11 (second metal plate) shown in FIG. 5, the protrusion as shown in FIG. Since t does not protrude from the ring surface, when the fan is housed in the same casing, the height H of the blade can be increased by the amount of the protrusion, and the amount of blown air can be increased. Furthermore, the present invention can be embodied in various forms without departing from the spirit or main characteristics of the present invention. Therefore, the above-described embodiments are merely exemplifications in all respects, and should not be construed as restrictive. I won't.

するものである。As described above in detail, according to the present invention, the protrusion formed on the first metal plate is inserted into the hole formed on the second metal plate, and then the protrusion protrudes from the second metal plate. Second, since the metal is pressed and deformed and pushed into the inclined portion formed around the hole, secondly, the protruding portion disappears from the surface of the metal plate, and the appearance is improved. Therefore, by applying this metal plate joining method to the casing and fan of the centrifugal blower, the casing and fan processing costs can be reduced, and the number of assembling steps can be significantly reduced. In addition, the projecting portion does not project from the side plate after the casing is assembled, and thus it is possible to prevent the projecting portion from being damaged by an operator.
