WIPO Patent Application WO/2022/009831
Kind Code:
A1
Abstract:
This guidance device is provided with: a raceway member; and a movable member which is engaged with the raceway member while having a plurality of rolling elements sandwiched therebetween. The movable member has formed therein a lubrication path for supplying a lubricant to a circulation path for the rolling elements. The circulation path comprises: a common path that includes an inlet part serving as a feed opening for the lubricant; a first path through which grease flows; and a second path through which a lubrication oil flows. The second path is configured to have a cross-sectional area smaller than that of the first path, and, in the common path, a second communication section of the second path is positioned closer to the inlet part side as compared with a first communication section of the first path. The guidance device is further provided with a plug member for blocking the inlet part of the common path. The plug member is removable and is capable of being moved within the common path.
