Abstract
A fan shaft seat structure including a shaft bushing and a heat dissipation member. The shaft bushing has an open end, a closed end and a, connection section. A receiving space is defined between the open end and the closed end. The connection section extends from the closed end in a direction reverse to the receiving space. The heat dissipation member has a first face and a second face. The first face is flush with a first end of the connection section in contact with the closed end of the shaft bushing. The second face is flush with a second end of the connection section. The shaft bushing is integrally connected with the heat dissipation member to increase heat dissipation area and save working time and manufacturing cost as well as achieve better heat dissipation effect.
