The invention provides an electric suspension device which does not interfere with mass production even if a linear motor is used as an electromagnetic actuator and suppresses manufacturing cost as much as possible. A first electric suspension device (11A) is provided between a vehicle body and wheels of a vehicle, and is provided with a first electromagnetic actuator (13A) that generates a driving force related to vibration attenuation of the vehicle. The first electromagnetic actuator (13A) includes a cylindrical rod member (21), and a frame body (31) provided so as to be capable of moving forward and backward in the axial direction with respect to the rod member (21) so as to surround the rod member (21). The rod member (21) includes a conductive shaft (23) and a cylindrical tube portion (25) surrounding the shaft (23). One end of each of a plurality of rod-side armature coils (27) provided to a rod member (21) is connected to a shaft (23). Power is supplied to a plurality of rod-side armature coils (27) provided to the rod member (21) via a shaft (23) of the rod member (21).

    本发明提供一种电动悬架装置,其即使在作为电磁致动器使用线性马达的情况下也不会妨碍批量生产,而尽可能地抑制制造成本。第1电动悬架装置(11A)设置在车辆的车身与车轮之间,并具备产生与车辆的振动衰减相关的驱动力的第1电磁致动器(13A)。第1电磁致动器(13A)包括圆柱状的杆部件(21)、和以包围杆部件(21)的方式相对于杆部件(21)在轴向上进退自如地设置的框体(31)。杆部材(21)包含具有导电性的轴(23)和包围轴(23)的圆筒状的管部(25)。在杆部件(21)上设置的多个杆侧电枢线圈(27)的一端与轴(23)连接。向在杆部件(21)设置的多个杆侧电枢线圈(27)的供电经由杆部件(21)的轴(23)进行。
