PROBLEM TO BE SOLVED: To provide a rail oil pullback device which can suppress contamination on an external part due to oil from a guide rail, and which can reduce an oil supply amount to the guide rail.SOLUTION: A rail oil pullback device 10 comprises: an oil guide member 20 having an oil reception port 21 for receiving at least a part of oil which is dropped from a guide shoe 7, an oil outlet 22 arranged below the oil reception port 21, and an oil guide surface for guiding the oil from the oil reception port 21 to the oil outlet 22, and being arranged so as not to relatively move to the guide shoe 7; and an oil pullback member 40 having an upper air inflow port 51 into which air flows when the guide shoe 7 is lifted up, a lower air inflow port 52 into which air flows when the guide shoe 7 is lifted down, and an air port 53 for blowing the flowed air so that at least the part of oil moved to the surrounding of the oil outlet 22 is scattered to a side face of the guide rail, and which is arranged so as not to relatively move to the oil guide member 20.SELECTED DRAWING: Figure 2
【課題】ガイドレールからの油で外部が汚損することを抑制でき、ガイドレールへの油の供給量も低減できるレール油引戻し装置を提供すること。【解決手段】レール油引戻し装置10が、ガイドシュー7から滴下した油の少なくとも一部を受ける油受口21、油受口21よりも下方に配置される油出口22、及び油を油受口21から油出口22に案内する油案内面を有して、ガイドシュー7に対して相対移動不可に配設される油案内部材20と、ガイドシュー7が上昇する際に空気が流入する上側空気流入口51、ガイドシュー7が下降する際に空気が流入する下側空気流入口52、及びそれらの流入した空気を、油出口22の周辺に移動した前油の少なくとも一部がガイドレールの側面に飛散するように吹き出す空気吹出口53を有して、油案内部材20に対して相対移動不可に配設される油引戻し部材40と、を備えるようにする。【選択図】図2
