|1. (WO2018221333) MOTION GUIDING DEVICE|
|Applicants:||THK CO., LTD.
|Title:||MOTION GUIDING DEVICE|
This motion guiding device 10 is provided with a lubricant supply pathway which is disposed in at least one of a pair of lid members 17 provided to a moving member 13 and which is for supplying a lubricant to an endless circulation path, wherein the lubricant supply pathway is at least provided with: a first lubricant supply pathway α that is formed so as to extend, from at least one of right and left lateral surfaces of the lid members 17, in a direction orthogonal to the longitudinal direction of a raceway member 11; and a second lubricant supply pathway β that is connected to the first lubricant supply pathway α, wherein the pathway shape of the second lubricant supply pathway β at a portion connected to the first lubricant supply pathway α is formed as an expanded-diameter hollow section 17c formed to have a larger diameter as compared with the shape of the rest of the pathway. This configuration enables providing a novel form of lid member that can be applied generally to a variety of specifications where a tunnel-shaped lubricant supply pathway is to be formed toward the central part from the right and left lateral surfaces of a lid member.
