Provided is a gradual stopping device for work machines capable of suppressing swaying of loads and shortening stopping time. The device comprises: a first gradual stopping means (21) for calculating a load sway cycle (T) when a stop signal is input and stopping an actuator (10) over the half cycle time (T1) of the load sway cycle (T); a second gradual stopping means (22) for stopping the actuator (10) over a time (T2) that is shorter than the half cycle time (T1) for the load sway cycle (T); a load sway predicting means (23) for predicting whether the load sway width (A) exceeds a permitted value; and a switching means (24) for switching between the first gradual stopping means (21) and the second gradual stopping means (22) according to the prediction of the load sway predicting means (23). Load sway when stopping the operation of a work machine can be suppressed, and the time required to stop the operation of the work machine can be shortened.
