Abstract
PURPOSE: To suppress generation of electric noise between armature and brush by shielding the motor.
CONSTITUTION: The motor 3 is shielded by covering it with a non-conductive case 1, providing a metal layer 3 between the inner side of the case 1 and motor 3, providing a metal plate 5 capable of being brought into contact with the metal layer 2, mounting a penetration type capacitor 9 on the plate connecting a brush through the penetration type capacitor to the power source. With this construction, in which an interference wave generating section constituted by the armature and brush of the motor is shielded by the metal layer provided on the inner side of the non- conductive case, metal plate and penetration type capacitor, interference waves leaking to the outside are very weak.
