To provide an electrically-driven cylinder device as one example which can suppress leakage of fluid due to a pressure difference at low cost.SOLUTION: An electrically-driven cylinder device as one example comprises: a housing provided with a cylinder and a release chamber communicated with the outside; a piston movably arranged in the cylinder to partition the cylinder into a fluid chamber and an intermediate chamber; a rotating member arranged between the release chamber and the intermediate chamber, and rotating around a rotary shaft; and a direct-acting member that moves in a shaft direction along the rotary shaft in response to the rotation of the rotating member to press the piston. A first hole which extends in the shaft direction and into which a component is fitted and a second hole which extends in the shaft direction and which communicate the release chamber with the intermediate chamber are formed in the rotating member.SELECTED DRAWING: Figure 1
【課題】一例として、圧力差による液体の漏出を低コストで抑制可能な電動シリンダ装置を得る。【解決手段】実施形態に係る電動シリンダ装置は、一例として、シリンダと、外部に連通する開放室と、が設けられたハウジングと、移動可能に前記シリンダに配置され、前記シリンダを液室と中間室とに区画する、ピストンと、前記開放室と前記中間室との間に配置され、回転軸まわりに回転する、回転部材と、前記回転部材の回転に応じて前記回転軸に沿う軸方向に移動することで前記ピストンを押す直動部材と、を備え、前記回転部材に、前記軸方向に延びるとともに部品が嵌め込まれる第1の孔と、前記軸方向に延びるとともに前記開放室と前記中間室とを連通する第2の孔と、が設けられる。【選択図】図1
