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.
摘要翻译：可动铁心（71）形成为具有与轭铁（51）相反的可动铁芯的表面积减小的停止位置的区域，该停止位置由电磁吸引力与复位弹簧（70）超过某一位置。因此，当可动铁芯（71）停止在一定位置时，可动铁心（71）的较大直径部分的外圆周表面面向磁轭，并且磁通量按照设计通过磁通道。但是，当可动铁芯（71）停止超过一定位置时，可动铁心（71）的大直径部分和小直径部分面对磁轭（51），并且可动磁芯的大直径部分的外周区域面向轭（51）的铁心（71）减少。因此，磁通变得难以通过磁通道并且电磁吸引力降低。结果，即使当对线圈施加过电流时，可动铁心也较少被吸引到接近或抵靠固定铁芯，并且可以抑制由剩余磁性引起的控制性能的劣化。

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.
