摘要

An electromechanical carbon brush 1 applied against a conductive rotating body 2 has a brush base material which is a material made of an aggregate including carbon as at least one (1) ingredient and of a binder, the electromechanical carbon brush 1 containing 0.2 to 10 % by weight of a water-soluble lubricant, 0.2 to 3 % by weight of fluorine denatured silicone oil or 0.2 to 10 % by weight of the water-soluble lubricant and a metallic compound, relative to the brush base material.
