A thin-thickness variable resistor is provided, which is capable of stabilizing electrical connection between metallic terminals and a resistor by increasing the holding strength for a second terminal by a substrate while preventing the bending strain during the bending work from spreading to a conductive portion conductive to the resistor. Said centrifugal wheel further comprises blades that are disposed in a substantially radial orientation relative to the axis of rotation, and a lateral disk on which the blades are retained with a lateral edge. If a cancellation request is detected at the receiving end, the cancellation agent locates the identified communication and deletes same.
