ため、自動組立が難しくなるという問題があった。However, in such a conventional example, the iron core 1 and the yoke 4 are caulked or press-fitted to each other, so that the contact area between the iron core 1 and the yoke 4 is small and the contact portion is not formed. Since it is stable, there is a problem that the magnetic attraction may be deteriorated and a predetermined suction force may not be obtained. Further, in the case of caulking, there is a problem that dimensional control is difficult due to caulking deformation and the assemblability is not good, and since the fitting tolerance of the iron core 1 to the yoke 4 cannot be made large in order to suppress caulking deformation, automatic assembly is not possible. There was the problem of becoming difficult.
