Provided is a bed device with which a bed baseplate can be inclined in left and right directions when a back bed part is in a raised state. This bed device is provided with: a swinging frame which is supported on a bed frame in such a way as to be capable of inclining, and on an upper surface of which a bed baseplate is provided； a drive source for swinging which drives the swinging frame in such a way as to incline in a width direction； a drive source for back lifting which is provided on the swinging frame and drives one end portion side in the longitudinal direction of the bed baseplate to be raised or lowered； and a control device which controls the inclining drive of the swinging frame and the raising and lowering drive of the bed baseplate. The control device controls the drive source for swinging and the drive source for back lifting in a manual mode in which, when either one of the swinging frame and the bed baseplate is in a horizontal state, the other can be driven, and a manual restricted mode in which, when either one of the swinging frame and the bed baseplate are driven in a restricted range, the other can be driven in a restricted range.本發明提供一種床裝置，可於已使背床部立起的狀態下，使床板體往左右方向傾斜。床裝置具備：搖動框架，可傾斜地支撐於床框架，並且於上表面設置有床板體；搖動用驅動源，驅動搖動框架往寬度方向傾斜；背升起用驅動源，設置於搖動框架，將床板體的長邊方向的一端部側進行起伏驅動；及控制裝置，控制搖動框架的傾斜驅動及床板體的起伏驅動。控制裝置藉由手動模式及手動限制模式，來控制搖動用驅動源及背升起用驅動源，其中手動模式可於搖動框架及床板體中之一者處於水平狀態時驅動另一者，手動限制模式可於搖動框架及床板體中之一者在限制的範圍內被驅動的狀態下，在限制的範圍內驅動另一者。
