BEARING HOUSING OF SMALL-SIZED MOTOR

摘要

PURPOSE:To eliminate cutting process and accurately obtain inexpensively a bearing housing of high quality by forming a housing base of a metal plate, and integrally molding the housing of synthetic resin with the base. CONSTITUTION:A housing base 21 having threaded holes 21a, 21b for mounting a stator yoke and a chassis is formed of a pressed metal plate. A bearing housing 22 for positioning and holding a bearing is integrally molded by injection molding synthetic resin around the base 21. Thus, the strength of the metal is provided for the housing, and the accuracy of the bearing can be held highly without cutting.
