Abstract
A second electric suspension device includes a second electromagnetic actuator that is provided between the vehicle body and a wheel of a vehicle and generates a driving force for damping vibration of the vehicle. The second electromagnetic actuator includes a columnar rod member and a casing surrounding the rod member and being provided capable of moving forward and backward relative to the rod member in the axial direction. Casing-side armature coils are provided in the casing in the axial direction, whereas magnets are provided in the rod member in the axial direction in such a manner as to face part of the casing-side armature coils in the casing. The magnets are formed by permanent magnets and electromagnets including rod-side armature coils.
