To provide an electric suspension device capable of preventing abnormal noise and disturbed behavior of the vehicle from occurring even when switching setting of control modes.SOLUTION: An electric suspension device comprises:an electromagnetic actuator 13 for generating driving force associated with a damping operation and an expansion and contraction operation: an information acquisition part 43 for acquiring each of information of the drive force and control mode selection information associated with the electromagnetic actuator 13; a driving force operation part 47 for setting a predetermined control mode based on the control mode selection information associated with the electromagnetic actuator, as well as for setting target damping force and target expansion and contraction force associated with the electromagnetic actuator 13 on the basis of the setting information associated with control mode; and a drive control part 49 for performing drive control of the electromagnetic actuator 13 using the target driving force which is set by the driving force operation part 47 on the basis of the target damping force and the target expansion and contraction force. The driving force operation part 47 performs a setting-switching operation according to the predetermined control operation during a time period when the driving force Fdr associated with the electromagnetic actuator 13 is converging into a predetermined force area FA.SELECTED DRAWING: Figure 3
