To provide a hydraulic power unit that can reduce hydraulic oil consumption and simplify a manufacturing process.SOLUTION: A hydraulic power unit comprises: a tank for storing hydraulic oil; piping for sucking the hydraulic oil stored in the tank; and a filter provided at a suction port of the piping to prevent foreign matters mixed in the hydraulic oil from entering the piping. The tank has a bottom surface section having an upper step section and a lower step section at different heights, the lower step section is formed entirely on the bottom surface section of the tank over a first direction, a step is provided between the upper step section and the lower step section in a second direction of the bottom surface section of the tank, and the filter is disposed in the lower step section.SELECTED DRAWING: Figure 3

    【課題】作動油の削減が可能であり、製造工程の簡略化が可能な油圧パワーユニットを提供する。【解決手段】作動油を貯留するタンクと、タンクに貯留された作動油を吸入する配管と、配管の吸入口に設けられ、作動油に混入した異物が配管に侵入するのを防ぐフィルタとを備える油圧パワーユニットを構成する。そして、タンクは、上段部と下段部とからなる高さの異なる底面部を有し、底面部において、下段部がタンクの第1の方向の全体にわたって形成され、タンクの底面部の第2の方向において、上段部と下段部との段差が設けられ、下段部にフィルタが配置される。【選択図】図3
