際に、接触状態が変化し、ノイズの原因となりやすい。The elastic force of the cylindrical ring 4 clamps the outer periphery of the cylindrical conductor 3 for grounding. However, the elastic force alone cannot provide a sufficient clamping force, and as a result, the cylindrical conductor 3 is grounded. The point contact between the cylindrical ring 4 and the cylindrical ring 4 is likely to cause poor contact. Moreover, as described above, when the rotational force is transmitted from the cylindrical conductor 3 to the cylindrical ring 4, the contact state changes, which easily causes noise.
