To provide a hydraulic device capable of effectively removing fine particles such as dust in a reciprocatory channel in which an operating fluid flows forward and backward, and an injection molding machine.SOLUTION: A hydraulic device is used for an injection molding machine, and is provided with a hydraulic circuit in which an operating fluid flows. The hydraulic circuit has a reciprocatory channel 1 in which one directional flow F1 of the operating fluid and the opposite directional flow F2 of the operating fluid are generated. The reciprocatory flow channel 1 includes a plurality of branched channels 2a and 2b which are formed by branching into two or more branches on a way and joining together, and each of which takes charge of either one flow of the one directional flow F1 of the operating fluid or the opposite directional flow F2 of the operating fluid. A filter 5 is provided in at least one of the plurality of branched channels 2a and 2b.SELECTED DRAWING: Figure 1 【課題】作動液が往復する往復流路で、粉塵等の微粒子を有効に取り除くことができる液圧装置及び射出成形機を提供する。【解決手段】液圧装置は、射出成形機に用いられ、作動液が流動する液圧回路を備えるものであって、前記液圧回路が、作動液の一方向の流れＦ１及び作動液の逆方向の流れＦ２の生じる往復流路１を有し、前記往復流路１が、途中で二股以上に分岐するとともに互いに合流し、それぞれ前記作動液の一方向の流れＦ１又は前記作動液の逆方向の流れＦ２のいずれか一方の流れを担う複数の分岐流路部２ａ及び２ｂを含み、前記複数の分岐流路部２ａ及び２ｂのうちの少なくとも一つに、フィルタ５が設けられてなる。【選択図】図１
