However, when a pair of left and right slots are punched out at the connecting corner between the bowl-shaped portion and the flange portion of the rotor member as in this prior art, the strength of the rotor member is reduced accordingly. In order to avoid the decrease in strength, it is necessary to increase the plate thickness of the rotor member or increase the height dimension of the rotor member, which results in increased manufacturing costs and larger size.

Furthermore, by punching and forming a pair of left and right slots in the connecting corner between the bowl-shaped part and the flange part of the rotor member, chip-type variable resistors can be automatically mounted on printed circuit boards in electrical equipment. When suctioning with a vacuum suction type collet, air is sucked in from the pair of left and right slots, so there is a problem that suction by the vacuum suction type collet is uncertain and suction errors occur frequently. .
