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.
