PROBLEM TO BE SOLVED: To provide an inter-motion member structure that is suitable for recovering lubricant evaporated under vacuum environment.SOLUTION: An inter-motion member structure B1 of this invention comprises a first member 4; a second member 5 that can be moved relatively in respect to the first member 4; a relative motion mechanism 6 installed between the first member 4 and the second member 5 so as to perform a relative motion of the second member 5 in respect to the first member 4 in a prescribed direction under presence of lubricant 64; seal means 7 arranged at either one of the first member 4 or the second member 5 so as to form a closed space S among the first member 4, the second member 5 and the relative motion mechanism 6; and cooling means 8 arranged in at least one of the first member 4 and the second member 5 so as to cool the lubricant 64 vaporized within the closed space S. With such a configuration as above, it is possible to prevent vaporized lubricant from dispersing into external part and at the same time to elongate a life of the relative motion mechanism by returning vaporized lubricant to the relative motion mechanism. 【課題】真空環境下において気化した潤滑剤を回収するのに適した相対動部材間の構造を提供する。【解決手段】相対部材間の構造Ｂ１は、第１部材４と、第１部材４に対して相対動可能な第２部材５と、第１および第２部材４．５の間に介装され、潤滑剤６４の存在下で第２部材５を第１部材４に対して所定方向に相対動させるための相対動機構６と、第１部材４または第２部材５のいずれか一方に設けられ、第１部材４、第２部材５および相対動機構６との間で閉じた空間Ｓを形成するためのシール手段７と、第１部材４および第２部材５のうち少なくとも一方に設けられ、閉じた空間Ｓの内部において気化した潤滑剤６４を冷却するための冷却手段８とを備える。このような構成によれば、気化した潤滑剤の外部への拡散を防止するとともに、気化した潤滑剤を相対動機構に戻すことにより当該相対動機構の長寿命化を図ることができる。【選択図】図３
