To increase the stability of a transferring device when a person to be cared for is transferred.

The transferring device 100 is a transferring device to transfer the person to be cared for. The transferring device 100 computes the position of the center of gravity of a system of mass points including a plurality of mass points corresponding to at least the person to be cared for and the transferring device, and computes the position of the center-of-gravity projection point located in the position where the center of gravity of the system of mass points is vertically projected with respect to a touchdown surface at which the transferring device touches down. A center-of-gravity position computing section 71b computes the position of the center-of-gravity of the system of mass points. A center-of-gravity projection point position computing section 71c computes the positions of the center-of-gravity projection points. The practical use of the positions of the center-of-gravity projection points permits the stability of the transferring device to be increased at the time when the person to be cared for is transferred.
