To provide technology that increases the accuracy of diagnosing a fault in the drive source of a work device.SOLUTION: A diagnosis device of the present invention indicates to a work device equipped with an object to be driven, a first drive source constituted so as to move the object to be driven in a first direction and a second drive source constituted so as to move the object to be driven in a second direction that cancels out the movement in the first direction, that the object to be driven be moved in the second direction by the second drive source while it is indicated that the object to be driven be moved in the first direction by the first drive source (S101); collects measured data obtained by measuring the action of the first drive source while the first drive source is actuated so as to move the object to be driven (S102); and diagnoses the state of the first drive source (S104) using the collected measured data (S103).SELECTED DRAWING: Figure 7 【課題】作業装置の駆動源に対する故障診断の精度を高める技術を提供する。【解決手段】診断装置は、駆動対象物、駆動対象物を第１方向に移動させるように構成された第１駆動源、及び第１方向への移動を打ち消す第２方向に駆動対象物を移動させるように構成された第２駆動源を備える作業装置に対して、第１駆動源により第１方向に駆動対象物を移動させるように指示している間に、第２駆動源により第２方向に駆動対象物を移動させるように指示し（Ｓ１０１）、駆動対象物を移動させようと第１駆動源を動作させている間に、第１駆動源の動作を計測することで得られる計測データを収集し（Ｓ１０２）、収集された計測データを利用して（Ｓ１０３）、第１駆動源の状態を診断する（Ｓ１０４）。【選択図】図７
