Zusammenfassung:The metal graphite grounding brush including silver is made in slide contact with a peripheral surface of an axle and grounds the axle. The mass ratio between silver and carbonaceous components including a volatile component in the brush is silver above 30% and up to 90% and carbonaceous components less than 70% and down to 10%. When the total of silver and carbonaceous components is made 100%, the volatile component is down to 2.0% and up to 15%. The brush grounds the axle reliably so that noise from a car radio is reduced and has a long service life and mechanical strength.
