摘要： A power tool has an electric motor with a stator assembly and an armature rotatable within the stator assembly. A commutator is rotatable with the armature and is connected to the armature via a shaft. The commutator has an outer layer formed from a titanium graphite material. Brushes are associated with the commutator and are held in an end plate. The brushes are formed from a titanium graphite material.

摘要： A rotary electronic component capable of reducing an abrasion and a metal fatigue of a slider and extending a rotation life time compared to the conventional technology. A rotary electronic component is provided with a buffer member between a sliding portion of a slider and a rotor. Thus, the sliding portion is energized toward the annular electrode with a proper elastic force and the sliding portion is held. Because of this, vibration of the sliding portion is suppressed and metal fatigue of the slider can be reduced. Furthermore, since the lubricant is impregnated into the buffer member and a part of the buffer member is in contact with the annular electrode, the lubricant can be applied on the annular electrode. Consequently, the sliding portion slides smoothly and the abrasion of the contact portion can be further reduced. In addition, since the buffer member functions to wipe the surface of the annular electrode, foreign substances such as dust on the annular electrode are collected. Thus, harmful effect to the contact portion by the foreign substances can be prevented. By the above described configurations, the rotary electronic component of the present invention can obtain the extended life time and high operation reliability.

摘要： 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.
