PURPOSE:To commonly use an end bracket by forming the end bracket of a steel plate integrally with a cylindrical surface, a rectangular end surface, a recess and a curved surface. CONSTITUTION:A cylindrical surface 50 for effectively holding a ball bearing, a rectangular end surface 51, an escape 52 formed continuously to the inside of the end surface 51 and a curved surface 53 for holding a metal bearing formed continuously to the inside of the escape are integrally formed by pressing with an end bracket 5. When the ball bearing is used, the ball bearing 16 is press-fitted until the outer wheel is contacted with the end surface 51. In this manner, a motor having the ball bearing can be provided, and the strength of a bearing support can be improved. |
