PROBLEM TO BE SOLVED: To provide a relative motion member which has a plurality of members relatively moving, and which can control frictional resistance when the members move.SOLUTION: A relative motion member includes a first member made of an insulator, a second member relatively rotatable to the first member and made of an insulator, and a lubricant filled in a space between the first member and the second member. The lubricant includes an ER fluid, and in the space, one or a plurality of electrodes for forming an electric field including a vertical direction component with respect to a relative motion direction of the first member and the second member are respectively provided in the first member and the second member.SELECTED DRAWING: Figure 1
【課題】複数の部材が相対運動する相対運動部材において、当該複数の部材の運動時の摩擦抵抗の制御が可能な相対運動部材を提供する。【解決手段】絶縁体からなる第1部材と、該第1部材に対して相対運動可能な絶縁体からなる第2部材と、前記第1部材と前記第2部材との間に位置する空間に充填された潤滑剤と、を有する相対運動部材であって、前記潤滑剤はER流体を含み、前記空間に、前記第1部材及び前記第2部材の相対運動方向に対して垂直な方向成分を含む電界を形成するための一又は複数の電極が、前記第1部材及び前記第2部材のそれぞれに設けられている相対運動部材である。【選択図】図1
