Abstract: A commutator portion or a brush of a motor is formed of electrically conductive resin. When making the commutator portion with electrically conductive resin, a commutator member is molded of non-electrically conductive resin and the commutator members are all integrally formed with the commutator support member. At this time, at least a portion of the outer periphery of the axle is formed simultaneously with an electrically conductive resin layer.

Abstract: An evaporator control valve is capable of opening a diaphragm in a desired pressure, thereby preventing a fuel tank from being deformed owing to negative pressure in the fuel tank, and also the evaporator control valve is provided with a solenoid for diagnosing trouble capable of forcibly opening or closing the diaphragm only at the time when an evaporating system is diagnosed.

Abstract: In a solenoid valve comprising a first solenoid valve for regulating pressure and a second multifunctional solenoid valve integrated with the first solenoid valve, even if a solenoid of the first solenoid valve is energized, a diaphragm valve of the solenoid valve is not immediately opened, thereby providing a safe and compact solenoid valve. The first solenoid valve comprises a first spring provided between the upper end of a plunger which is movable by the solenoid and stator, while the lower end of the plunger is disposed to be brought into contact with the diaphragm valve and a second spring is provided for urging the diaphragm valve in the direction to close it even if the plunger is moved away from the diaphragm valve and the second solenoid valve which is integrated with said solenoid valve for controlling to selectively open or close a closing valve and a one way valve.
