PROBLEM TO BE SOLVED: To provide an inspection method capable of inspecting oil pressure in parallel with other inspection items even when a one-way clutch is built-in in an electric driving device.SOLUTION: Steps ST17 and ST20 for checking whether a foot shaft performs reverse rotation by instructing an electric motor to inversely rotate the foot shaft, and a step ST14 for checking whether an oil pressure reaches a prescribed pressure are performed. Wire connection can be confirmed by checking the rotation direction of the electric motor. No abnormality in an oil pressure system can be confirmed by checking the oil pressure. That is, the present invention allows collective checking of wire connection and oil pressure. 【課題】ワンウエイクラッチを内蔵する電動駆動装置であっても、他の検査項目と並行して油圧の検査が行える検査方法を提供することを課題とする。【解決手段】足軸が逆転回転する指令を電動モータに与えて、足軸が逆転回転するか否かを調べるステップ（ＳＴ１７、２０）と、油圧が所定圧に達しているか否かを調べるステップ（ＳＴ１４）とを実施する。電動モータの回転方向を調べることで結線の確認ができる。油圧を調べることで油圧系に異常がないことを確認できる。すなわち、本発明によれば、結線確認と油圧確認とを一括して行うことができる。【選択図】図６
