摘要： A rotation sensor functioning as both a rotation-angle sensor and a torque sensor is provided which, when applied to a steering sensor for an automobile, for example, permits reduction in the number of components and thus in the weight of the automobile and contributes to conservation of global environment. The rotation sensor has slip rings covered with conductive synthetic resin having small coefficient of friction, allowing the contact pressure of brushes disposed in sliding contact with the slip rings to be kept low and the life duration of the slip rings to be prolonged. Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.

摘要： 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.
