Abstract: A contact type rotation sensor includes a contact brush having a contact and an electrical resistor disposed for sliding motion relative to the contact. The contact brush provided at a side face of an arm portion with a projecting piece has asymmetric shape and asymmetric weight distribution about its longitudinal axis, and is large in moment of inertia in a direction of torsion. During relative sliding motion, suppressed torsional vibration of the contact occurs not only at natural frequencies but also at dispersed frequencies other than natural frequencies, reducing the sound pressure of sliding sound. A stable contact state is ensured between the contact and the electrical resistor, resulting in improved durability.

Abstract: With a resistor, a variable resistor, and a method for manufacturing a resistor according to the present invention, it is possible to eliminate lead and prevent deterioration of sliding characteristics. A resistor according to the present invention is disposed on an insulating layer. The resistor has: a more-conductive-material-containing layer containing more conductive materials than insulating materials; and a more-insulating-material-containing layer that does not contain lead and that contains more insulating materials than conductive materials. The more-conductive-material-containing layer has a polished surface. For example, the film thickness of the more-conductive-material-containing layer in a low-resistance region having a resistance value smaller than or equal to a prescribed value is larger than the film thickness of the more-insulating-material-containing layer in a high-resistance region having a resistance value larger than the prescribed value.
