Abstract: 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.

Abstract: A vehicle driving apparatus is provided that includes a drive motor, an internal combustion engine, and an electrical generator and can inhibit a weight balance and motion performance of a vehicle from being deteriorated and lowered. A vehicle driving apparatus driving a vehicle by motive power of a motor, the vehicle driving apparatus including a drive motor that is driven by electric power, an internal combustion engine that produces motive power by fuel, and an electrical generator that is driven by the internal combustion engine, the vehicle driving apparatus being characterized in that the drive motor, the internal combustion engine, and the electrical generator are arranged in a vehicle width direction of the vehicle in order of the drive motor, the internal combustion engine, and the electrical generator.
