Abstract
An unmanned aerial device according to an aspect of the present invention includes an aerial device body capable of flying in an unmanned manner, and a load-lowering device mounted to the aerial device body and configured to lower a load from the aerial device body. The load-lowering device has a linear member holder for holding a linear member having one end portion connectable to the load, the linear member holder holding at least the other end portion of the linear member, and a speed limiting mechanism that limits a speed at which the linear member is pulled out of the linear member holder, under a weight of the load.
