    摘要: A movable core (71) is formed to have such an outer shape that the surface area of the movable core opposite to a yoke (51) is reduced in the region where the stop position, which is determined by balancing between the electromagnetic attracting force and a return spring (70), exceeds a certain position. Thus, when the movable core (71) is stopped in the certain position, the outer circumference surface of a larger-diameter portion of the movable core (71) faces the yoke and the magnetic flux passes through the magnetic passage as per designed. But when the movable core (71) is stopped beyond the certain position, both large- and small-diameter portions of the movable core (71) face the yoke (51) and the outer circumference area of the larger-diameter portion of the movable core (71) which faces the yoke (51) is reduced. Therefore, the magnetic flux becomes hard to pass through the magnetic passage and the electromagnetic attracting force is reduced. As a result, the movable core is less attracted to come close to or abut against the stationary core even when an overcurrent is applied to a coil, and deterioration in control performance possibly caused by residual magnetism is suppressed.

    摘要: An intake air throttle valve device is capable of statically determining the opening of a throttle valve by balance between a driving force from a motor and an elastic force from an elastic member, thus making it possible to prevent the occurrence of a range in which it is impossible to control the opening of the throttle valve in accordance with the amount of electric power supplied to the motor. The intake air throttle valve device of the present invention is provided, in an intermediate portion of the elastic member with a load applying element for causing the elastic member to generate a force to oppose the force of a throttle gear thereby to apply a load to the throttle gear. The load applying element includes a third engagement portion, a first abutment portion and a second abutment portion.
