摘要：
In an oscillation type linear actuator for reciprocally moving a plurality of moving members held in parallel with each other in a predetermined direction owing to electromagnetic action between a stator and them, two moving members reciprocally moving in opposite phases with each other are coupled by a coupling member having spring function, and a non-displacing portion of a plate spring portion of the coupling member which is not displaced substantially is restricted by a stopper. Even when an external force is applied to one of two moving members reciprocally moving in the opposite phases each other, motion of the other moving member is transmitted to the moving member via the coupling member, so that reduction of amplitude of the moving member to which the external force is applied can be restricted, and a balance of amplitudes of two moving members is maintained. Furthermore, since a component having the plate spring portion is used as the coupling member, it is possible to downsize the oscillation type linear actuator.

在由于定子和它们之间的电磁作用而使预定方向上彼此平行地保持的多个移动构件相互移动的振荡型线性致动器中，通过联接器相互反向移动的两个移动构件 具有弹簧功能的构件，以及基本上没有位移的联接构件的板簧部分的不移动部分被制动器限制。 即使当外力对相互相反的相互移动的两个移动部件中的一个施加时，另一个移动部件的运动经由联接部件被传递到移动部件，从而使移动部件的振幅减小到 可以限制施加的外力，并且保持两个移动构件的振幅的平衡。 此外，由于使用具有板簧部分的部件作为联接构件，因此可以减小振荡型线性致动器的尺寸。
