壊、ワレ、ヒビ入り等の不具合があった。Using the conventional manufacturing method of bending a single metal plate to create a "pleat shape," it is extremely difficult to manufacture multiple V-grooved pulleys σ1 with different diameters. Regarding multi-stage pulleys with different diameters, a method was used in which five multi-V grooved pulleys with different outer diameters were manufactured in advance and the two were joined by welding, etc., but this This method has the disadvantage that the strength of the welded part is slightly weak, so it is easy to break during use, and the conventional method involves folding and crushing a single piece of metal material to form a peripheral wall, followed by rolling the grooves. In such cases, the metal crystals on the peripheral wall grow in different directions, and it is difficult to make the strength of the material uniform, causing buckling of the metal material. Groove σ] There were defects such as destruction, cracking, and cracking.
