PURPOSE:To decrease mandays on assembly by installing a bracket made of a resin monolithically molding a stator core, a stator coil, a brush holder and a bearing housing. CONSTITUTION:A stator coil is wound, a terminal 40 is fitted, the whole is set into a resin molding die together with a core 28, and a bearing housing section B32 is monolithically molded to the upper section of the coil end 31 of the core 28, a brush holder section 33 in the rectangular direction of the coil end 31 and a ventilating hole section 34 around the core 28 with a resin, thus forming a bracket B30. An armature 35 is inserted into the bracket B30, end a bracket A36 to which an air guide section 38 us shaped integrally is fixed by a through bolt 39 while being brought into contact with the bracket B30. A brush box 13 in which a brush 14 is admitted is press-fitted and fastened to the brush holder section 33 for the bracket B30. A rotary fan 20 is fixed to a shaft 19, and a fan case 21 is press-fitted and fastened to the bracket A36, thus completing a fan motor.
