A suspension device (S) is provided with: an actuator device (AD) having an actuator body (A) capable of extending and retracting, the actuator body (A) being interposed between a spring upper member (B) and a spring lower member (W) of a vehicle, and a pump (4) for supplying a fluid to the actuator body (A) and extending and retracting the actuator body (A); and a controller (C) for controlling the speed of the pump (4). The controller (C) has a road surface condition indicator acquiring unit (41) for calculating a road surface condition indicator (I), and a target speed determining unit (43) for determining a target speed (Nref) for the pump (4) on the basis of the road surface condition indicator (I). 悬架装置(S)具备：致动器装置(AD)，其具有：致动器主体(A)，其安装于车辆的弹簧上构件(B)与弹簧下构件(W)之间，能够伸缩；泵(4)，其向致动器主体(A)供给流体而使致动器主体(A)伸缩；以及控制器(C)，其对泵(4)的转速进行控制。控制器(C)具有：路面状态指标取得部(41)，其求出路面状态指标(I)；以及目标转速决定部(43)，其基于路面状态指标(I)来决定泵(4)的目标转速(Nref)。
