PURPOSE: To provide a brushless motor which has made possible cost reduction by forming a bearing supporting mechanism through integration of a motor chassis and a bearing supporting member. CONSTITUTION: A cylindrical bearing housing member 31 is integrally formed to a motor chassis 21 by the deep drawing process and an oil-impregnated sintered bearing 32 is fixed with pressure to the bearing housing 31. A thrust receptacle 33 is arranged at the lower side of this bearing 32 to hold it with a thrust regulating plate 34 fixed at the lower side of the motor chassis 21 and a rotor shaft 28 is inserted into the bearing 32 and the end face is placed in contact with the thrust receptacle 33 for supporting with the shaft. |
