定した後、第５図に示す様に所定の形状に成形する。FIG. 4 is a schematic diagram showing the manufacturing process of the weight 2a according to an embodiment of the present invention. The strip material 6 is wound spirally a required number of times along the winding core 8 corresponding to the weight fixing horn 7, and then cut, and after fixing the winding ends by suitable means such as welding, as shown in FIG. Mold into a predetermined shape as shown.

良い。Thereafter, the state in which it is attached and fixed to the weight number horn 7 is shown in FIG. The amount of weight must be increased or decreased depending on the magnitude of the unbalanced load, but this is adjusted by changing the number of windings of the weight. Further, since the weight height H is constant regardless of the magnitude of the unbalanced load, it is sufficient that the length of the weight attachment horn 7 is one type.

平板状ウェイト２を重ねて使用すればよい。FIG. 7 is a sectional view of a rotor 1 using a weight 2b according to another embodiment of the present invention. The spiral way) 2a has a space 9 inside due to its structure, so when it is fixed with the weight attachment horns 7, there is a possibility that stable fixation may not be possible or that unnecessary dust may enter the space 9. In some cases, a conventionally used flat weight 2 may be stacked on top of the spiral weight 2a.

After the end of the winding is fixed by a means, it is molded into a certain shape and used as a weight, so that the following effects are achieved.
１）ウェイト用帯状素材６は１００％廟効に使用出来る
。1) The weight strip material 6 can be used 100% effectively.
２）ウェイトは全部あるいは大半が一つの塊状となるた
め、取付作業性が向上する。2) Since all or most of the weights are in the form of one block, installation workability is improved.
３）ウェイト量の調整は巻回数を変えることにより可能
となり、ウェイト取イマＪ用ツノ長さが一定となるため
エンドリング鋳造型が一種類あれば良くなる。3) The amount of weight can be adjusted by changing the number of turns, and since the length of the horn for the weight take-up J is constant, only one type of end ring casting mold is required.
