Abstract

PURPOSE:To reduce a working time and the number of processes and to lower a product cost, by forming a sleeve part to which a rotary shaft is inserted and a motor pedestal part on which the stator coil of a driving motor is mounted integrally. CONSTITUTION:The rotary shaft 20 is inserted to the inner diameter plane of the sleeve part 12 in a housing 10 consisting of the sleeve part 12 and the motor pedestal part 11 extending outward in a radius direction from the sleeve part 12 integrally. Between the outer diameter plane of the rotary shaft 20 and the inner diameter plane of the sleeve part 12 confronting with the above, a pressure type radial bearing is constituted, and between the lower end face of the rotary shaft 20 and the upper end face of a thrust bearing 15 confronted with the above and fitted in the sleeve part 12, a pressure type thrust bearing is constituted. Thus, since the motor pedestal 11 and the sleeve part 12 are molded integrally, it is possible to reduce the number of processes and the time required for working, thereby, to lower the cost.
