Abstract

The conductive ring (1) includes a conductive retaining member (10) that is annular around an axis (x), a conductive member (20) that extends around the axis (x), and a spring member (30) that extends around the axis (x). The conductive member (20) contacts the shaft and cooperates with the spring member (30) to generate a clamping force on the shaft. When the sliding distance (D) of the shaft relative to the conductive member (20) is a specified required sliding distance (D1), the interference fit (δ) of the contact becomes a specified value of interference fit (δ1).
