A carbon brush holder with improved air vents includes a body, a housing, and an exhaust lid, which are provided with corresponding fixing structures for their convenient assembly or disassembly. The exhaust lid is formed with a diverging air channel. By the exquisite configurations of the fixing structures provided on its components, the carbon brush holder is easy to assemble and disassemble so as to facilitate replacement or repair of parts settled in the carbon brush holder. Besides, since the exhaust lid in the present invention has the diverging air channel opened at two sides thereof as the air vents, it significantly improves the efficiency in dust expelling and heat dissipating, thereby effectively preventing the air vent from blocked and preventing overheat caused by poor exhaust. |
